One more comment. I think it’s safe to say he’s serious about some of the points (like that Bitcoin is focused on empowering oppressed people, while other protocols work on more trivial things), and that these are intended to offer some meaningful internal critique of the Ethereum community.
Even while he’s more tongue in cheek about other points: like the Kevin Pham bit, which honestly just makes maximalists look like dicks, and Ethereum people look like they can at least laugh at themselves.
Basically the whole thing is another Vitalik April 1 “meta joke” where he gets to watch people take the wrong things seriously, and contort themselves to criticise the correct things.
