Actually, you're right. That's exactly what it's like. The former is how your Government routinely invades your privacy; the latter is an unequivocal violation of the Fourth Amendment of the US Constitution. As it is with on-cloud versus on-device scanning. If Apple were compelled by the US Government to expand the on-device scanning to search for anything, that too would be an unequivocal Fourth Amendment violation. Whereas any scanning that occurs on the cloud is not subject to Fourth Amendment protection. It's excepted under the so-called "third party doctrine", which effectively means the Government can rifle through whatever they want for any reason.
