There's no ingroup or outgroup here. Cryptocurrency isn't people, and even cryptocurrency developers are perfectly able to host other projects there.

Community standards exist everywhere. Censorship implies the power to silence people, and in no way is Codeberg able to prevent people from sharing their project widely. They are an intentionally small platform supporting an open internet. This is no different than their long lived restriction on proprietary software. Which is again no different from Debian restricting what goes on their repos.

You can run proprietary cryptocurrency software on your own computer with both Debian and Forgejo (Codeberg's forge software), but neither project will host it for you.

And I question if the point of it is truely about protecting people or defining in-groups and out-groups and promoting ideological conformism.

My point is, who cares if this is part of the community's reasoning? All communities are defined by common beliefs.

its more telling that asking us to self reflect on what the contemporary left is evidently such a taboo.

Why do you feel like you can just drop that in without any explanation? Not everything falls into a left-right binary. Open discussions require both sides to be reasonable, you need to provide reasons for your claims, otherwise it's just noise.
