For anyone who cares, Bluesky is not meaningfully decentralized and can be easily censored.
Mastodon cannot be censored in the same way, thus no long-term enshittification. If you're going to switch away from Twitter, give Mastodon a try. It uses the same tech/protocol as Lemmy, Piefed, Loops, Pixelfed, m/kbin, etc.
it's basically twitter.
I will say, the cool thing about it is the interoperability between ActivityPub platforms. For example, from my mastodon account, since I'm subscribed to some hashtags I'm interested in, I occasionally see posts from Lemmy/Piefed (reddit-like), Pixelfed (Instagram-like), Loops (Tiktok-like), etc. I can comment and like without having to create accounts on the other platforms. It's definitely more aligned with what the open web should look like, although could use some UX and discoverability improvements, as I'm not entirely sure how some stuff works, but it's been interesting to try it out.
