Hypocrisy and arrogance at its finest - its ok for us to engage in illegal spying but not other countries. US leads the world in illegal activities and spying/stealing from foreign nations.
That's one of those empty, non-falsifiable statements that don't do anything to further a discussion. Spying and illegal activities are by definition supposed to be secret.
But it also doesn't matter. Because...

... as a matter of general principle: it's in the best interest of a country to know what other countries are doing and to protect its own assets. There is no contradiction in doing both at the same time.
If a country suspects that one of the cornerstones of its communication infrastructure is at risk of being infiltrated by a foreign power, it makes sense to take steps to avoid that.
I'll leave it to others to judge whether or not that principle applies to the Huawei case.
The US does not view China as an ally, it's a competitor that the US sometimes cooperates with economically.
The US and its allies are saying they prefer to keep the spying inside their own allied domain. That's not only entirely rational, it obviously makes perfect sense from a national self-interest standpoint.
As an American, if I get to choose, I'm buying my 5G tech from European or Asian allies. I'll happily pay more for it.
The US isn't saying China can't spy, it's universally understood that China is spying and will keep trying to, just as the US will. The US is basically openly saying it's going to attempt to counter or limit that spying, because China is a global rival in all regards. Just as China will always attempt to limit the ability of the US to spy on China and its interests. The same goes for Russia and its spying, going all the way back to the early days of the USSR.
