No… NO. It was appallingly terrible at banning Nazis, worse than even Reddit in many ways. Twitter banned a tiny, tiny fraction of extremely prominent and openly fascist accounts that had been permitted to operate for years, but they ignored Nazi dogwhistles from large accounts and smaller accounts that didn’t gain a following and were used to harass 1-2 people were generally allowed to operate freely.
Remember: they didn’t even ban Donald Trump himself until he tried to literally violently overthrow the US government. Twitter pre-Musk was an absolute shit hole, but it was at least headed in a hopeful direction. Musk kept it a shit hole and just changed the direction it was going.
It would be funny if he started a Mastodon instance with whatever his values are. The reason he would never do that is because it’s not for profit.
