Most of them don't like Mastodon either due to not liking defederation drama, but instead they moved their socializing to Discord and Instagram, with a few chomping at the bit to get into BlueSky.
For what it's worth, this is a trend I observed long before Twitter introduced rate-limiting and the login gate. Ironically, clicking through on Twitter links other people posted was the one use case I ever visited the site for, and now that that doesn't work I simply rely on the vxtwitter summary or a screenshot.
But now they blocked checking things when not logged in, inertia has set in and I cannot even bothered to make the effort and don't feel like I've lost anything. Even for those accounts I followed.
I just think of paid blue checks spouting off nonsense while paying to do so and think to myself: "No ... that's not the bullshit I want to consume. I preferred the relatively democratic bullshit from before"
... and then I think: "Let's just cut the bullshit"
It is a shame, as it was entertaining.

Looks like Twitter is just easy to bash nowadays, I'm not that a big user but I see, especially in the OSS / computer related profiles a lot of people putting their Mastodon address in the nickname and yet still tweeting, retweeting, liking in the same compulsory manner as they did before.
