If I’m interpreting the quote correctly, it’s because if they have to exclude the EU because of competition laws, that implies they know it’s anticompetitive in some eay, yet roll it out elsewhere anyway.
Which shouldn’t be surprising though, if companies refrained from anticompetitive behaviour because they think it’s wrong, we wouldn’t need these laws.
China has an active genocide going on, recently effectively annexed Hong Kong, and is threatening Taiwan. They’re also a dictatorship, while the US at least has some semblance of democracy. A country like that exerting their power over the world unchecked seems in no way better. Probably not really worse than the US either, at least whenever there’s a republican president.
