People fundamentally use Facebook differently than twitter, even if fb can be used as a public square, most ppl still use it to network with ppl they know (or used to know). Whereas twitter’s entire use case is talking to people who you’ve never met and likely never will.

The point is that engagement is very different and no one cares about verification on fb. Editable posts have been a thing for years and I’m blanking on what other features are per of twitter blue but I doubt it’ll be enough to charge people $19.99/m
