You may be thinking of Lundy et al v. Meta Platforms, in which they were not fined but agreed to a civil settlement and denied they were doing what was claimed. In that cases, it wasn't even alleged that they were trying to make the locations of specific individuals available for human analysis.
Meta was fined for violating consumer privacy for years, which TikTok has already been doing themselves; but as you can already see they have become even worse than Facebook.

You see, even when Meta didn't get fined for that, perhaps it's about time for TikTok to get fined in the billions for violating consumer's privacy in the US and repeated offences should be in the tens of billions of dollars to discourage such activity in the US?
Tiktok and Facebook both should be fined for violating the law when there is sufficient evidence that the violation happened. We don't need to make up stories about Facebook to justify investigations into either.
An imperial, totalitarian regime which currently imprisons people for being of a specific ethnicity (or any arbitrary reason), and has no measure of a proper judicial system, tracking citizens of other nations for purposes of pursuing their power - is not the same thing as - Facebook making it possible for advertisers to target groups of people with 'interests'.
Meta can be fined for shenanigans (which FYI mostly do not cause direct harm), and of course - we need better regulations.
But the issue of TikTok is one of national (frankly international) security, and it's on an entirely different level.

Tik Tok exists as a corporation for people to "do business in China" AKA be paid vast sums of money for knowledge and skills that would be treason or whatever to otherwise transfer.
At least Facebook people keep up appearances -- pretend to be a capitalist, then shun any regulations or taxes that differentiate capitalism from oligarchy.
(And Federal Trade Commission is a joke, it's a known thing they can often do one test case when a behavior is being done in parallel across industry by many actors.)
More privacy w.r.t. those wouldn't hurt non-US countries, I would say.
