Free as in freedom has had a rather specific meaning in software for the past 40+ years, which is "software that matches the Free Software definition." Codeberg runs on Forgejo, whose authors grant you the rights to run, study, modify, and distribute it - unlike GitHub, which is proprietary. (Indeed, there are many Forgejo instances besides Codeberg, it's not just a theoretical benefit.)

It is a ridiculous misinterpretation to assume it means "somebody else will host anything I upload, free of charge", which is of course not the case - not on GitHub either, by the way, their ToS just happens to be more friendly to slop.

(For understandable reasons, too; while M$ is making a killing from selling LLM access & Free Software as training data, the main "benefit" Codeberg sees is getting DDoSed by LLM scrapers 24/7 and vibecoders using up disproportionate amounts of resources.)
