> that data is being exfiltrated

Multiple bits of information are exfiltrated actually, and to a 3rd party (if it turns out the behavior is as described). The obvious one is your IP, which allows for some coarse geolocation. Also implicitly they would know you're running macOS.

The main thing this breaks down is that it assumes that if you have a QR code with a URL saved, then you must trust the target enough to let them see your IP. However, clearly not everyone agrees.
