Firstly, the US government has greater authority and ability to fine or otherwise leverage financial action against companies incorporated in the US.

But never does it with Facebook and not over gathering data, your reasoning for banning TikTok.

Secondly, Facebook leadership has been repeatedly called to testify in Congress for various reasons in recent years

A slap on the wrist resulting in no significant changes and nothing to do with gathering data.

In August of last year they paid out $725 mil in a class action lawsuit.

Not the U.S. government. You could have the same lawsuit against TikTok.

Although not US, still NATO example

Irrelevant, other NATO countries are not currently trying to ban TikTok.

They were also recently called to testify in front of US congress about the online child exploitation crisis.

As above, a slap on the wrist resulting in no significant changes. Also, nothing to do with exploitation of data.

they are getting punished for mismanagement, both publicly and financially.

Slaps on the wrist are not punishment and they are not being punished for gathering data. They also make more revenue every single year. They haven't lost any money.

It may be a drop in the bucket, so to speak, but it’s been enough for them to change their policies and practices over the years.

They have not changed any of their data gathering policies except to make them so that they can gather more data.

Stop changing the subject. You said TikTok is getting banned by the government for data gathering. I told you Facebook is not being punished by the government for doing the same thing. All you can do is sue them. Just like you could sue TikTok if you could get a case together.

You have not showed me to be incorrect.

Sorry... your evidence that Facebook would be held accountable in America, unlike TikTok, is a fine they were levied in Europe?
