No need to specifically demonize China...
...If one of the TLAs isn't either suborning or actively collaborating with one or more US-based social media giants I would be very surprised.
Why wouldn't China be spying using anything it can get to undermine its rival or spy on its military capabilities and readiness? Especially since it's perfectly legal over there.
To me, it's less about the fact that they're spying, and more about the fact that they're spies working for a hostile foreign government. That's the sticking point for me. I don't care where you stand on the globe - the real question is: is your government hostile to my interests? If so, I won't trust anything that comes out of your country, and you DEFINITELY should have a healthy distrust of anything that comes out of mine.
