It's not semantics at all. The "scope" is infinite. The government can get pretty much any information that exists pursuant to a valid warrant or subpoena. That has been true since the founding of the republic, and was true in England for hundreds of years before that.

What matters is how direct that access is. Does the government have to submit a warrant to get user-specific data, and then gets that data back in a drop box like system? Then there's nothing illegal, surprising, or even sketchy about that. Can the government get direct access to Facebook's servers without going through their legal department? Then that's a big deal!
