I mean, if you think like that, then it doesn't really matter at all. Americans aren't so bound to concept of Chinese face that they actually even care about this. Since we don't get face hurt, accusations of hypocrisy are pretty pointless anyways.
Saving face is not just about saving face. There's also your credibility at stake. There's only so many times you can invade a country under false pretenses before the international community, or even your own constituency, starts siding with the opposition. I guess also if we really don't have any principles anymore, we'll have devolved back to survival of the fittest principles. At which point we don't need thinkers, just people doing what they can to get what they can all the time. No need to argue or make points. Just fight it out and save some time.
China said "American companies not welcome in China's internet", well they didn't say it, they just made that the truth. America saying "Chinese companies not welcome in America's internet" 10 years later isn't going to raise many eyebrows abroad. For the most part, people are wondering why it took so long.

China has been very clear that the principle should be tit for tat. All of their economic and foreign policy is based on that, from the visas they issue to visitors, the tariffs we exchange on vehicle production, and the foreigners they throw in prison when one of their own is put on house arrest in Canada. This is just a very late counter-reaction to a policy China has held for awhile.
It's the sovereign right of any country to be protectionist. Protectionism is actually the default. Open markets is not the default. I'd like to think the open US market is what makes it great, and too much protectionism actually stifles innovation and the robustness of the domestic economy.
The US market hasn't historically been that open. We started this country with tariffs as the only thing funding the government. All the free trade market stuff we have today was carefully negotiated via the WTO, and even then there is a huge bias in supporting allies (remember, when China opened up in the late 90s, it was antagonistic with Russia and actually a US ally since the the late 70s, that is all history now).
