We can all rant and rave at YouTube's policies, but the truth is we need YouTube more than they need us. Losing a few crypto-influencers means nothing in the grand scheme of things. YouTube have your habits, watch history, search history, basically your life. They know what to push infront of your eyes as alternative media. There's no stopping the Google/YouTube juggernaut.
I don't agree with your statement that we need youtube more than he needs us. Youtube itself has been working on crypto ads for long times before decide to ban crypto channels.
The policy of youtube has been changed simultaniously with facebook banning crypto. It's clear that giants of ads [youtube/facebook] either want to curb the spreadness of cryptocurrencies as both of them has an alternative,Libra for facebook and google cards. Or they obey the policies applied by legal authorities which is still trying to maximum limit the existence/use of crypto.
