Microsoft saw a world
That's not what happened. They got a dominant position because IBM could not even on their IBM PCs, and were at the right place at the right time, even if DOS was actually just garbage. With the power/money from this deal, they strongmanned their position as dominant PC operating system long after that era using legal and illegal anti-competitive means.
Microsoft still has wide unethical reach with secret and not-so-secret contracts and agreements not to allow other operating systems to gain a foothold in OEMs. And that's before you get through the sheer inertia from users that completely refuse to try something different on the grounds that they don't want to.
Besides this, the complete apathy in Europe moving off Microsoft software is quite concerning. Companies in the US are already collaborating with fascists in an unreflected way in true capitalist fashion - as happened 90 years ago. The reaction to this in terms of OS selection by companies is to hide their head in the sand and pour concrete for good measure. This will not work indefinitely, and I feel like nobody is going to suffer consequences for being a completely willful useful idiot for what is in summation a batshit fascist regime.
Yes, I am putting Microsoft and fascism on the same pedestal, the end stage in Microsoft bashing. The sad part with this meme is that in 2025 it's not unwarranted.
Nobody has ever been fired for ordering ~~SAP~~ Microsoft, right?
Nobody disputed that their current software works.
The issue in this case is that the vast majority of companies will choose a tool made by a company that will now be bending their will to a fascist dictator whose cronies cannot be trusted to do rudimentary operational security.
There was always the nebulous stranglehold that the US might have on the IT security of any company that chooses Microsoft, because you cannot build Windows and the vast majority of their software from source, or audit them.
From the IT security perspective of Europe it's exactly like all zero-days and backdoors known and implemented by the US intelligence agencies were just handed over to North Korea.
