Where is this doom and gloom coming from?
Wikipedia isn't ending. Legal challenges can be dealt with as they always have, and in the worst-case scenario the org can move countries if necessary. I can't even imagine why you "expect the slow ramp of anti wikipedia rhetoric". Where is this coming from? Even if something happened to the org, some other org can clone it -- content and infrastructure and all.
And college students still have to cite their sources, and I don't even know what that has to do with Wikipedia, which isn't something any college student should be citing directly anyways.
Your pessimism doesn't seem to be based on any kind of facts, unless I'm missing something here? Especially with the inaccuracies of LLM's, people continue to care about correct knowledge, and so people will continue to use and update Wikipedia. Heck, LLM's may even make Wikipedia more important than it's ever been before.
