Codeberg is one public flagship instance. They are not neutral and don't claim to be. Decisions on what to host are made via elections by e.V. members. Other platforms (GitHub, GitLab, Tangled etc.) will eventually run into this same thing as well, e.g. how GitHub responds to DMCA requests, the difference with Codeberg is that there are elections which decide on what gets hosted on the main instance. For hosting slop or running a ton of actions, the recommendation is to self-host Forgejo directly instead, meaning that you, not the e.V. pays for the consequences, and you'd use the future AP federation support for cross-instance support. Forgejo is particularly simple to self-host as well, and lots of people do it (ffmpeg, Fedora and more). That way, you get to set your own rules and e.V. election results have no effect on you.
