Facebook absolutely would sell your info to foreign governments, however I'm not convinced Google would.

I know Google harvests a shitton of data and uses it for advertising, but that's ironically why I think they probably wouldn't actually sell it. Because Google owns a massive advertising company, it's in their best interests to keep the data they collect so that other companies can't pop up and use the data themselves.

Also, if I'm not mistaken, the bill isn't specifically about tiktok but instead covers the sale of personal data to foreign countries in general. It's just that it's worded in a way that tiktok is the obvious target. As such, I'm not sure an American company could sell their customer's info to China; at least not without laundering it through other companies first.

However, all of that said, I'm not trying to defend the bill, tiktok, Google or Facebook. I don't like any of those companies and while I think the concept of the bill is good, it's very obviously focused on tiktok and, like you and others have pointed out, does nothing about the data collection that American companies do.
