I thought Snowden already made it pretty obvious that US companies don’t. Basically the only thing you can do as a US company is try to obfuscate your data with encryption so not even you can read it. That’s why some VPN companies advertise about not keeping laws, so they have nothing to turn over when the feds come a-knocking.
The other problem is that you don’t even need official government power to get data from US companies. A lot of these companies will sell their data on you to make a quick buck, anyway.
