I'm a bit surprised it's not higher.
Everything they've done is to increase their profits revenue. While some people may have left as a protest, the vast majority of people don't really care - see: twitter, facebook, instagram, tiktok. If anything, the "bad news" about people leaving was great advertising for them.
What I've observed over the past ten+ years, and still don't understand, is how anyone enjoys the platform at all. At one level, I get that it's just another social media platform that promotes headlines and memes. But the voting system and the engagement is revolting. I'm not going to say it's 80% bots but I will say that 80% of people using social media might be dumber than the bots.
I deleted my account in 2023. I have to admit that there are few if any reasonable alternatives for some of the subs existing there. The Fediverse really doesn't satisfy the need for people to get semi-expert opinions on things, for example.
