I did decide to delete all my comments and posts on Reddit. Sure, maybe I've posted some helpful comments, but why support Reddit with their continued existence? Remove content, and people might move to other sites to get their information.
I also decided to keep my account. Turns out some content stayed around, because I could not see and therefore delete it in locked subreddits. So when they came back, the comments came back too, and I was able to delete them, still.
There's been a hostile takeover at Gitea and it's now run / owned by a for-profit company. The developers forked the project under the name Forgejo and are continuing the work under a non-profit. See also: Their introduction post and a page comparing the two projects. Feel free to look up more, since I haven't familiarized myself with the incident all that much myself. Either way though, maybe consider using Forgejo instead of Gitea.
