Codeberg is making decisions to better manage their resource and infrastructure. It's no different than any other privately owned platform, making decisions to forbid certain kinds of content, or ban people for various reasons. Unlike other large centralized platforms, they at least tried to involve the community in this decision-making process, but in the end it's their call.

If you don't want to be under the mercy of someone else's decisions, you have to become more independent and host it yourself. Even then, who owns your server? Who owns the "pipes" of the network? They have terms of services, and can also ban you for various reasons, including your nationality, beliefs, etc. This line of thinking leads to a bigger question of how/whether a truly decentralized and free (as in freedom) computing and communication network is possible, how such a network can defend against abuse and malicious actors without compromising that freedom.
