Both the American and Chinese governments have bad track records when it comes to abusing civil liberties, privacy intrusion. I would say that the Chinese government is worse, but that doesn't really matter from my perspective for this particular thing.

As an American, I expect that the US government, if it wants it enough, can obtain access to my communications (at least while using US infrastructure), assuming they're not e2e encrypted. Hopefully such access would be gated by a warrant, and I expect in most cases that's how it works, though I do expect there are abuses here and there.

The Chinese government, however, should not have any kind of access to any of my communications (unless I am visiting China, using their infrastructure; or perhaps am communicating with someone in China from abroad). In addition, if the relationship between the US and China ever sours to the point of war, presumably the Chinese would have no problem using any possible backdoors to disrupt US telecom networks.

Given this, I would much rather the US use US-built telecom infrastructure than Chinese-built infra. I think an argument over which government is more moral or trustworthy is just not useful here.
