Private Cloud Compute servers have no persistent storage so there would be nothing to see upon opening the kimono. You'd need some sort of government requested live wire tap thing to harvest the data out of the incoming requests, which might be a different situation. I'm, of course, just some dude on the internet, thinking up a counter-point to this concern, who knows if I am even remotely in the right ballpark.

It doesn't actually say there is no persistent storage, it says that the compute node will not store it for longer than the request. There's nothing to stop the data coming from a datastore outside of the "PCC" in another part of apple's infrastructure.
Speaking of tech, has anyone ever independently audited Apple's encrypted infrastructure a-la what they're promising for Private Compute? I'm unconvinced that the government couldn't crack that if they wanted.
