I found it interesting that congress never took issue with any other social media platform, and was fine with TikTok once again as well after it was sold to an American owner.

So looks like politicians never had any problem with the addictiveness of social media, they only have a problem when it's used by foreign adversaries and not by domestic companies...

Absolutely no one was running it on "social media is harmful". The policy was overtly that it had to be American owned.
