The US government can definitely compel US tech companies to give out information on users, they do regularly.

What evidence do you have for this claim? Are you saying the they can request user data arbitrarily?

>But Facebook policy also allows for “emergency requests,” where the tech giant will voluntarily hand over data outside of the legal process when police claim a case involves death or “potential bodily harm.” Increasingly, law enforcement has taken advantage. In 2019, the government made 6,447 such “emergency requests,” compared to 6,000 in 2018 and 3,672 in 2017. Police submitted “preservation requests,” which operate outside of the legal process and preserve user data for 90 days, for more than 110,000 accounts in 2019.

I'm surprised you haven't heard of this by now, its been known for years. Of course you can say police will only use it in "real emergencies" but you're not the one defining what a "real emergency" is and cops lie constantly just to get information

>Are you saying that the US government can compel these companies to take certain actions in the same way that the Chinese government can? Like, as in, being able to force the company to give up all of its users' private details?

There is reasonable evidence of this happening. For example: what happened with Qwest. The former CEO claims this was the primary reason for him being targeted. He was openly against the spying by the NSA before the charges were filed. https://www.foxbusiness.com/features/former-qwest-ceo-joe-na...

Are you claiming that because the US has the ability to get individual user data in law enforcement investigations, they also have the authority to get all of their user data?
