Why is he so hated here? Twitter model is one thing that is kinda fit for global-open-decentralized approaches without much difference for the user. I could never use it, but plenty of people do and seem to have a feeling of hivemind over it.

This is the advantage of decentralization over federation. IMHO the fact that Lemmy is only federated really hurts it. Not so much for user accounts (in theory these can be backed up restored and moved. Not ideal but not awful) but in that communities are tied to servers. When the server a community is on goes away it is hugely damaging to that community.

don't you avoid taxes anyway if you're not profitable?

Techno King Asshole. TKA for short.

I kinda agree Twitter was born of a more innocent age, and he was just a tech kid with a good enough pitch to get Silicon Valley VC. The problem is that he did little to rein in powers that were purposely using the platform for social manipulation. Then -- when he already knew better -- he went and started Bluesky, which he specifically said was going to counteract all of Twitter's deficiencies, but capitalism got the better of him, so to make the platform attractive to VCs, advertisers, whatever, his team started to ditch what made Bluesky unique in favor of business tools to help it make money. Business is gonna business, it's not 100% his fault, but I can't imagine what will change a 3rd time around.

I think the main one is that Nostr is supposed to be really simple, and derive some security/privacy from that simplicity. Whereas ATProto and ActivityPub store and forward content so that each rely has a copy, on Nostr nodes the messages are all ephemeral. So it has something of a following with crypto bros and privacy enthusiasts. With nostr IDs are also based on public/private keys unlike ATProto/ActivityPub that use a username@instancename scheme, so signing and identifying content that belongs to a user is easier and more guaranteed to be correct, and your username isn't tied to any specific server "instance"
