Because this imaginary world where the US somehow equally controls Facebook on the level that China directly influences TikTok isn’t one that exists?
This low resolution view of the world is grating. “Facebook is a US based social media company so it’s exactly the same as China and TikTok” is completely devoid of the context of reality.
Not only does Facebook actually have 1st amendment speech rights with a judicial system empowered to enforce them. But even the slightest appearance that the US government was attempting to influence speech on Facebook would be a career ending scandal.
Compared to TikTok where the CCP literally has a seat on ByteDance’s board by law and has for its entire existence had its algorithm nuke political topics that China does not want discussed.
It’s not the same thing.
