Straining to assume good faith here but this seems very likely to be wilful misinfo - particularly given the emphasis. The reasons for the fork are very clearly stated in the lettter linked in the comment you're replying to: it's about community decision-making procedures (which have been removed during the incorporation). It's also about profit: the US corp is for-profit.
Secondly, not only are Codeberg a non-profit, they also adopted the project after the fork. That wasn't a part of the original letter nor discussion. They don't control the project (see aforementioned objections on the basis of democratic input) - they're a host & benefactor.
