What do you mean by losing free CI running? Codeberg has two free-of-charge CI offerings: Forgejo Actions and Woodpecker CI.
Forgejo Actions is enabled by default for all accounts. Woodpecker does require an explicit access to be granted, but it's fast and easy to request. You just create an issue here: https://codeberg.org/Codeberg-e.V./requests
Big projects like Zig have managed to migrate to Codeberg: https://codeberg.org/ziglang
