Again, I see little difference between the PRC and USA in this regard. As an American, I couldn't care less about Chinese surveillance. But my own government has an active interest in monitoring my politics for thoughtcrime and influencing my thoughts and actions. Making a moral panic only about the foreign platform seems, itself, like propaganda.

And this is a model you feel should be implemented here?

Signal isn't exactly trustworthy here either. Signal still likes to brag about the times when they told the government they couldn't hand over the data the feds wanted because they never collect/store it in the first place, but a long time ago they started collecting and permanently storing in the cloud exactly that same data. Worse, they refuse to update their privacy policy to reflect what they've started doing, meaning that the very first sentence of that policy is an outright lie. Personally, I take that as a massive dead canary and assume that signal has been completely compromised.

There are alternatives out there which I hope still deliver on the promise of allowing secure communications, and we're free to roll our own, but I strongly suspect that the US gov will move in on anything that gains enough of a following.

I think that we're still far better off than the Chinese, but we're not as free as we pretend that we are.

Social media companies have also their own nefarious goals so you don't have only to worry about your government but also about the (un)intended consequences of attention capitalism
