I run Gitea too - Seeing what is happening over at GitHub solidifies my decision.
Not too concerned over my public facing repos, Amazon and OpenAI seem to love 'em!
I have the ultimate control over my private repos (nothing juicy). I can't say I trust Microsoft not to do something I don't like at any point in the future.
Edit: I should say I wish phabricator got more love, that was a great tool!
I personally am self-hosting. Going anywhere else that is central again would just shift the shit-pile somewhere else. At least with self-hosting I know that my code is not used for AI training.
