What will happen to overseas people who depend on WeChat if the US and other countries truely block them?

It appears some say it’s due to political reasons as many major US global sites are blocked on the flip side causing them to create thier own. I believe if not they wouldn’t had created TikTok or Doyuan. Or WeChat for that matter. And would likely just use American or international sites.

I do notice despite Reddits normal lean the nostupidquestions sub seems more populated by MAGA folks. But social media as a whole seems changing vs 10 years ago.
