There's nothing ironic, weird, or surprising about the US wanting to stop other countries from doing to them what they do to other countries. It's hypocritical in some sense, mostly because the US tries to project itself as the good guys, but it's just basic international relations. That's how every country has always operated and will always operate.
The US mostly tries to project itself as "the good guys" to its own inhabitants, and secondly to the local and international media. But in most of the world you are often faced with the business end of a US-operated or US-financed weapon.
The thing is, its subjects are mostly non-citizens, so it's enough to grind _those_ into a pulp. So far, the US has not seen a popular uprising which threatens the stability of the state(, excluding perhaps that of the native Americans, who were actually ground to a pulp, eventually).
People seem to take for granted that things like that will never change, but always is a very long time --much longer than modern history. I hope you don't just expect/accept that we should kill ourselves off as opposed to reaching some kind of sustainability.
Right, the decision to avoid huawei is totally justified, but the hypocrisy is something to behold. Even here on HN, where people supposedly shouldn't be falling for propaganda so easily, there is a lot of indignation when e.g. the Chinese are caught doing something shady. If someone then points out that this is in some sense normal and US agencies are doing the same or worse stuff it is instantly dismissed as whataboutism.
