Reminder: TikTok is not actually important. Everyone can live their lives without TikTok, YouTube, etc. There's an infinite amount of ways to entertain ourselves and there's a lot of competing apps.
This isn't the government abusing its power to shut down some small business/upstart. It's shutting down a serious national security threat and a monopoly. TikTok has abused their position many times in many ways, refused to cooperate, and has reached the, "find out" phase.
