Images trigger CSAM obligations, CSAM obligations make it super hard for small players to scale. Also images lead to video, and video (especially bandwidth) means everything starts to cost a lot, hosting and CDN serving naturally starts to centralise. For text-only nostr, really anyone can join in on the infra side, it's so insanely cheap. Unrelated, but if you could go back in time would you still call it nostr? If not, what would you call it instead?
