Dunno for sure, I feel the same way as you, but I think it's more about "I refuse to use the app you intended me to be forced to by killing [favorite 3rd party app].
If combined with an adblocker they don't get your ad revenue but they do still get to add you to the tally of "active users", so I still feel abandoning ship altogether is best practice.
Yes and no.
Structurally, it'll remain decentralized, so one clear advantage here is that if the admins of a very large instance start trying something, my current understanding of how this works would let users ignore them. They don't control account creation, since any federated instance can see everything, so there's no meaningful way to actually block someone, they can make a new account and the rogue instance has no further powers to stop individuals. They could block whole instances that don't conform, but unlike Reddit, that doesn't get rid of them. Instead, it fractures the communities, which hurts everyone. In that case, a user protest wouldn't be a blackout like Reddit had, it would be a migration to another instance, and if other instances blocked them back, replacement communities would form.
Of course, this is a double-edged sword, it's harder for Lemmy to permanently end communities of hate and others that deserve permanent bans, as is always the case with decentralized authority, but that's the tradeoff.
Based on a Google search and the following link, no.
Google defined child porn using the term "sexually explicit conduct", involving a minor, fair enough, gotta look deeper.
Cornell has a legal definition of sexually explicit conduct for us, which basically breaks it into 5 categories, actual sex, bestiality, masturbating, specific kinds of abuse, and displays of various body parts.

If this would be CP, it'd have to be some kind of abuse or the display, and I don't think anything Nick aired would count as "masochistic" or "sadistic". The body parts listed are also specific and don't include feet.
So, in the US, it's just really creepy, not CP. the fact we have to delve this deep to determine it's not CP is pretty telling on its own, though.
