that tweet was not to throw shade at ethereum at all, it is cool and always will be, it is the high minded ideal cryptocurrency that Made It and became lindy

but on an individual level I have seen some of the worst and most wasteful behaviour in the emergent dao culture in pretended service of those ideals as a shield for total self service, the EF high minded model provided cover for emulative entities to act badly behind the scenes
also for the lotus project we were trying to let people mint NFTs by spending ERC20 tokens not eth. a popular new (at the time) protocol did this, we wanted to use their tech. I asked to use it, they delayed literally WEEKS getting back to me with no explanation. finally they got some lower level team member, some BD lady making $1m/year, who called me from a fancy brooklyn spot at peak hours just to show off. neither of us could hear each other on the call and she just bragged about the protocol for an hour before ghosting me forever
fortunately another ethereum protocol came out with the ability to mint NFTs for ERC20 tokens in the intervening time. they took 2.5% for the privilege (OF COURSE). they were pretty awesome, also arrogant about their high-minded decentralized ideals but at least they returned messages...
then the cease and desist came down, and they literally did the opposite of have our backs. they deleted a tweet supporting us, their legal team removed images I took of my own physical property from my page on their site, and then without warning or notice, complied with a frivolous, tortious DMCA removal request by the issuer of the c&d and took down our entire page where our users could see the amount of ETH they donated and how many tokens they'd get in return to mint our NFTs. then of course they ghosted us after an irked discord message from their founder.
so yeah there has been good stuff built on ethereum-- the defi that hasn't been hacked and has survived contagion, milady/remilia as culture, metalex as useful disruption, .
but soooooooooo much of it was a larp from self-interested dao-overpaid incompetent careerists huffing their own farts and quote tweeting vitalik longposts thinking they're doing something equally high IQ
