If TikTok and WeChat's usage becomes more widespread in the voting population of the US, they would have a lot of influence by controlling what kind of content its users sees; e.g., FB has been criticized many times for this, namely performing psychological experiments on its users
I recall this quote by former KGB informant Yuri Bezmenov:
> The main emphasis of the KGB is not in the area of intelligence at all. Only about 15% of time, money, and manpower is spent on espionage and such. The other 85% is a slow process which we call either ideological subversion or active measures ... or psychological warfare
The difference between TikTok and WeChat and FB/Google/Twitter is obvious: the former are to some degree controlled by China and the latter are private entities.
I understand there are services part of WeChat that are essential to users, so I would hope there is a good compromise here. I don't see why the communication component of the app can't continue to exist but WeChat is a lot more than a chat app.
