Yes. I used Boost until the blackout (June 12th or something like that). That date I uninstalled it and didn't log in anymore.
Then I waited until June 30th just to see if they've changed their plan. They didn't, so I replaced all my comments and then I deleted my account.
From that date I created an account first on KBin but I didn't like that they didn't show which server the threads were actually on, so I migrated to Lemmy world with wefwef. So far, really happy with the experience.
Kbin feels like it's trying to be both twitter-like and reddit-like. I was looking for something more along the lines of a drop-in replacement for reddit. Lemmy pretty much is that.
