Jack seemed interested in the protocol side of the house and making a good product that was in spirit of the internet, it also had a mix of people you might know IRL (with reasonable privacy defaults) and official sources/public figures. I don't think he was much interested in the censorship, it feels they got run over by a bunch of activist types during covid (who decided it was de rigeur to censor real doctors for perceived 'misinformation'). Jack started work on Bluesky and now is involved in Nostr

Speaking personally, supposedly Twitter now (X) still has a bunch of censorship and I don't especially like Musk (but what he did was valuable, showing Jay Bhattacharya he'd be put on a trending blacklist) and the site is... well, I should be able to follow threads without having an account but they crippled it so much. It reminds me of Instagram, "log in to see any PUBLIC page"
