I'm being nice about this and assuming Google (which also owns Youtube, and it shows, in their decisions about content) is just run by a bunch of naive people and isn't directly controlled by three letter agencies - they have to take a stronger stance against censorship/selective information

"Oh, but that doesn't happen" - it does, Goog results have been manipulated before to the extent that probably can't be attributed purely to SEO. Youtube removed tons of "covid misinformation" about things we all know now to be true
