Apart from arrogant hypocrisy about "control software on millions of devices" having Apple&Google totally controlling and having unlimited access to all iOS/Android devices in the world, there is something else.

Things could be much worse, really. Just imagine that China do absolutely nothing with TikTok recemmendation algorithm at all, and it just show most shared or liked videos for each region without any interference.

That what I would name a total disaster for US.

And this way China could get much more useful information about West than in case of whatever cheating. Clean and honest slice of audience preferences is much better than any artificially created one.
