Let me burst your bubble. YES, your government spies on you, not matter which party is in power, no matter which country, even progressive Europeans ones, if not they ask US to do the dirty job on their citizens for them. It is been always the same, in the 30's in the 40's in the 50's, 60's 70's 80's and on... It's part of the way a responsible government stops mass attacks against their own citizens, criminal activities and terrorism. It's part of our life. What we, as citizens must demand is accountability and a way to avoid abuses by our leaders in using those tools.
As for Tik-Tok, the problem is that that platform is used by some guys in the Chinese Government to spread chaos, confusion and anti-democratic ideas between our young generations, it's being abused by foreign assets.
And please don't compare USA with China, we don't have Uyghur's extermination and reeducation camps. Here we are still a democracy, a wounded one if you wish, but DEMOCRACY!
