I don't think they were saying that there aren't reasons to not use github, in or out of the USA, but rather that codeberg was already not a contender for many use cases due to their existing rules restricting private/non-OSS repos.
Are there any alternatives that you could use for closed source development that aren't owned by US entities?
What if you can't be bothered and would rather pay a symbolic subscription, like what github offers?
And then they wonder why they go bankrupt like those dignified German car manufacturers. It's because people can't afford them.
