So, everything you mentioned are reasons I’ve heard for people to switch from GitHub to GitLab, which is why I explicitly mentioned them both in the question.

So far no one has given me any advantage specific to codeberg. (Keeping in mind that GitLab is already open source, self-hosted, and federated via ActivityPub).

What exactly is the advantage of codeberg over gitlab and github? People just say “miscellaneous privacy benefits”

What was perforce’s solution to this? If you delete a file in a new revision, it still kept the old data around, right? Otherwise there’d be no way to rollback.

It has delayed it by several months at least though
