I’m pretty sure lots of mail gets x-rayed, perhaps even more looking for malicious packages or substances.

I agree that data content scanning is more invasive than physical scanning. It was an intentionally simplistic example not meant to defend Apple.

Parcels, maybe. I’d bet it’s a tiny percentage though.

I doubt the entire world has enough X-ray machines to scan even a vanishingly small percentage of the envelopes the postal service delivers every day.

Sorry my metaphor wasn’t good enough.
