This is funny, can you elaborate how come a ranking algorithm is a national security threat? It reminds me of the time when Google/FB/Instagram/Twitter still worked in China, Chinese govt used the same excuse to ban big tech social platforms.

Propaganda is powerful. If China wanted to send a message to change public opinion around the world tweaking the recommendation algorithm to do that would be a very helpful tool.

The CCP band western propaganda platforms, which Facebook etc could be said to be. Fine, I think any set of ideologies need propaganda, like every company needs advertisement.

If you understand that, then surely you must see the symmetry in banning Tiktok etc?

The great firewall should work both ways, otherwise it encourages more selective censorship.
