I have been on board with or ambivalent about most of the changes. I don't care if there's less moderation, I think Twitter probably did have too many employees, and I like the idea of a paid account with fewer (preferably no) ads. I'd even have happily paid Twitter to continue using Tweetbot.
But this has destroyed the trust and the user experience of many of the power users who are most engaged with Twitter and who make it a thing other people want to engage with.
I have sent 10,000s of Tweets but I can't see it being much more than a handful more.
I don't think Mastodon is a good replacement for Twitter at all, but I am going to have to try it. The fact that Tapbots are enthusiastically supporting it with Ivory is a good sign (though @tapbots, if you're listening, I'd happily donate 10x more to Ivory as an open source project than you'd make from selling it to me as a closed source app ;-).
