With thinking Facebook sucks? Nothing.
With thinking Facebook sucks and Facebook's audience should stay in Facebook while the "fediverse" stays small and exclusive? That it goes against the stated goals of providing decentralized, open social platforms as a replacement for current closed platforms.
The conversation doesn't start there, though. Before Threads was announced everybody was buzzing about how everyone should come over here and they really hoped new services would join ActivityPub and it should become just like email.
Then Threads and BlueSky started suggesting doing just that and it was all "actually, Google kinda EEE'd the crap out of email and RSS and we don't want those guys here at all".
So no, EEE wasn't always part of the converrsation. It was only part of the conversation when the hipstery claim that the cool obscure thing should be for everybody got replaced by the hipstery claim that the cool obscure thing was selling out and should be gatekept to keep it real.
