The discrepancy you're recognizing is surely due to astroturfing. I know it's an unsavory thing to point out, but it's also very obvious.
The US government should not be sending its data to a foreign adversary. Doesn't matter if we're talking about AI services or just general compute and data hosting. This is an obvious choice for obvious reasons.
When I worked with government agencies as a cloud engineer, we had to use AWS GovCloud. Like, we were forbidden from using non-GovCloud despite AWS being a US company. So with that level of security scrutiny being in-place well before LLMs became a thing, it is no surprise that allowing government employees to send sensitive information directly to the Chinese government wouldn't be allowed lol
