Thanks to the CLOUD act, its pretty irrelevant where the data is as long as its owned by a US entity.
The government can just force release, even if it's on European servers.
And what if it’s Chinese servers? Like, iCloud stuff but for Chinese nationals in China?
In this case it's a EU company serving either an EU built model or a Chinese model. For the Chinese models they are not forwarding the requests to China, the model is still running in EU.
