That language is not in the terms of service. The word "side" does not appear on that page.
The terms of service state:
> Private repositories are only allowed for things required for FLOSS projects, like storing secrets, team-internal discussions or hiding projects from the public until they're ready for usage and/or contribution. They are also allowed for really small & personal stuff like your journal, config files, ideas or notes, but explicitly not as a personal cloud or media storage.
The TOS Section 1:
> Our service is open for all projects covered by a licence for free and open source software, free and open source hardware, or free cultural works as defined by § 2 (1) 1.
So the "FUD" I am spreading is literally the headline of the legal terms of service. There is an organization behind the spread of this information, and it is Codeberg e.V.
