Apple could block 100% of the people using Beeper and throw Hackintosh users into that as a bonus as well.
The reason they’re not doing that is because it could have unintended consequences as some are using someone else’s actual device serial number and those people would be inconvenienced.
It’s nothing that can’t be easily solved, the moment they reach out to support either in person or via phone/chat Apple can immediately verify if they’re using a legitimate Apple device, but even if it boils down to a small percentage of users you still need to prepare for the influx of support requests.
To do this, Apple uses a scoring model to determine if they can access iMessage and historically they’ve been pretty generous by allowing clearly spoofed serials if the Apple ID involved is in good standing and has a positive history, think of it as a credit score. They can tweak the threshold score and probably are testing this out as we speak to find a sweet spot they’re content with.
Apple could also push out an update tomorrow that would end this once and for all by utilizing device attestation and leveraging Secure Enclave, but this would potentially lock out older devices, something they were willing to do when they upgraded the FaceTime protocol a couple of years ago, but they might not want to do that this time around.
