xkcd comics are available under a CC-By-NC 2.5 licence, so you've successfully pirated by not including attribution (as long as people can't tell at a glance that it's xkcd from the art style or comment thread you posted it to), but to seal the deal, it'd be a crime to sell it.

A Spud apologist! Sabotage by a scarecrow was beyond Bob's control, and the cause of most problems.
Most of the languages you've mentioned aren't systems languages, so don't make being a good language to write an OS in a high priority. More languages might be accepted in the future, but if they are, it'll be ones that are a natural fit for the problems they're solving.
Returns and refunds happened because the EU warned them that if they didn't, they'd create legislation so they'd have to, as they were already in a grey area under EU law. EA had a similar refund policy for games bought through Origin before Steam did.
Other than that, nearly everything you listed was done because it made business sense and would lead to more profit. Decoupling PC gaming from Windows by working on Linux means they're not at the mercy of Microsoft's whims, and was started at a time where it looked like Microsoft might make a version of Windows that could only install third-party software through the Windows Store. Discouraging kernel-level anti cheat discourages one of the last hurdles to Linux being able to play all Windows games. Supporting VR lets them still VR games through Steam.
Not being publicly traded lets them be concerned about their long-term profits above their short-term ones, so they won't do things that tarnish their reputation nearly as often as their competitors, and can do multi-year projects. They look good because their competitors are bad rather than because what they do is altruistic.
Edit: I just did some maths. The Steam Deck has sold somewhere around 5 million units and a Windows licence costs somewhere around $50 to an OEM with a volume licensing deal. Both these figures are approximate as I couldn't find precise numbers, but they're enough for a ballpark figure. This means that Valve have saved around $250 million by shipping the Deck with SteamOS instead of Windows. Even if my figures are way off, it's still a huge amount of money and goes a long way towards making all their work on Linux pay for itself.
Arch is at least more likely to update to a fixed version sooner, and someone getting something with pacman is going to be used to the idea of it breaking because of using bleeding edge dependencies. The difference with the Flatpak is that most users believe that they're getting something straight from the developers, so they're not going to report problems to the right people if Fedora puts a different source of Flatpaks in the lists and overrides working packages with ones so broken as to be useless.
People fall off rooftops fitting solar panels, burn to death repairing wind turbines that they can't climb down fast enough to escape, and dams burst and wash away towns. Renewable energy is much less killy than fossil fuels, but per megawatt hour, it's comparable to nuclear, despite a few large incidents killing quite a lot of people each. At the moment, over their history, hydro is four times deadlier than nuclear, wind's a little worse than nuclear, and solar's a little better. Fission power is actually really safe.
The article's talking about fusion power, though. Fission reactions are dangerous because if you've got enough fuel to get a reaction at all, you've got enough fuel to get a bigger reaction than you want, so you have to control it carefully to avoid making it too hot, which would cause the steam in the reactor to burst out and carry chunks of partially-used fuel with it, which are very deadly. That problem doesn't exist with fusion. It's so hard to make the reaction happen in the first place that any problem just makes the reaction stop immediately. If you somehow blew a hole in the side of the reactor, you'd just get some very hot hydrogen and very hot helium, which would be harmless in a few minutes once they'd cooled down. It's impossible for fusion power, once it's working, not to be the safest way to generate energy in history because it inherently avoids the big problems with what is already one of the safest ways.
PowerShell has a system to sign scripts, and with its default configuration, will refuse to execute scripts, and with the more sensible configuration you should switch to if you actually use PowerShell, refuses to execute unsigned scripts from the Internet.
I suspect that most of the scripts you're referring to just set -ExecutionPolicy Bypass
to disable signature checking and run any script, though.
That's misleading in the other direction, though, as PhysX is really two things, a regular boring CPU-side physics library (just like Havok, Jolt and Bullet), and the GPU-accelerated physics library which only does a few things, but does them faster. Most things that use PhysX just use the CPU-side part and won't notice or care if the GPU changes. A few things use the GPU-accelerated part, but the overwhelming majority of those use it for optional extra features that only work on Nvidia cards, and instead of running the same effects on the CPU if there's no Nvidia card available, they just skip them, so it's not the end of the world to leave them disabled on the 5000-series.
It does also get pushed by organisations that profit from fossil fuels as an excuse to never need to decarbonise as they can hypothetically just capture it all again later, which is dumb and impractical for a variety of reasons, including the one alluded to above. Some kind of Carbon sink will need to be part of the long-term solution, but the groups pushing most strongly want it to be the whole solution and have someone else pay for it so they can keep doing the same things as caused the problem in the first place.
A billion dollars worth of bitcoin isn't that much of the total amount of bitcoin any more, so any impact on the price would be because of people reacting emotionally to the news, not because they're was suddenly a flood of extra bitcoin in circulation.
The Free Software movement was generally a leftist objection to the limitations on computer use that capitalism was causing, and the open source movement was a pro-corporate offshoot to try and make the obvious benefits more compatible with capitalism (which it's been pretty successful at, even if it has reintroduced some of the problems Free Software was trying to stop in the first place). Anyone who's making a distinction between the two at the minimum is recognising that capitalism is why we can't have certain specific nice things, so it's not a huge leap to blame it for other problems, too.
As for a sensible middle ground, the Free Software movement designed its licences to work in the capitalist societies they operated in, so the incompatibility with corporate use has never been as big a deal as it's been made out to be. Corporations can use copyleft-licenced software just fine as long as they're not unreasonable about it. It's totally fine for a corporation to use a GPL tool internally and even have an internal fork as long as they put the source code for their internal fork on the company's file share so the employees using the tool can improve it if they get the urge. They can even sell products that depend on LGPL or MPL libraries if they make the source of the builds of those libraries they used available on their website or otherwise accessible to their customers (and use a DLL/.so
/.dylib
build of the library of it's LGPL). These restrictions are all less of a pain than making an MIT-licenced clone of an existing project, but companies have opted to make clones instead. The only bonus this gives them is that they can make it proprietary again later, and it has the added risk that one of their competitors could make a proprietary fork with a killer feature they can charge for, which isn't a nice risk. There are other benefits to investing in making your own clone of something, but they don't depend on the license it uses.
First, someone has to email licensing@xkcd.com to tell Randal Munroe that there's a potential licence violation so he can file a suit.
