I’m just thinking that the enshittification of Reddit has started, and once started it won’t stop.

Maybe, but network effects are powerful. Elon Musk, despite his best efforts, has not succeeded in driving away people from X-twitter, and I don’t believe that reddit will proceed as radically. There will be more adds, but the frog will be boiled slowly. I don’t see myself going back to reddit, but it’s more because I’m ideologically committed (I have been using exclusively Linux for 20+ years).
