This is obviously false.
Go check TikTok to see what shows up in searches for Tiananmen square or Uighur genocide, or even anyone of the many small catastrophes that go against the CCP's narrative.
You're claiming that consuming propaganda from a totalitarian regime that actively engages against your security, stability, and best interests is somehow better than consuming hypothetical propaganda from your own democratically elected government. Make it make sense.
Foreign propaganda is much less dangerous than domestic propaganda because domestic propaganda is more likely to relate to issues that actually matter to citizens.
It's not about what you care or don't care. It's about using China's social media service to discuss the very topics that China wants to censor. Again, go to TikTok or whatever alternative service provided by China and try to refer to the Tiananmen massacre or Uighur genocide. See what your paragons of free speech treat that.
