The thing with this service is, if I understand it correctly, that they were using someone else’s device ID to send messages.
So, say for example that someone started using my Mac Mini’s ID (my Mac being located in Madrid, Spain) to send iMessages in the US….
People expected Apple not noticing it?
It worked when it was some hacker’s project because at that time, a few stolen Apple device IDs didn’t raise too many red flags. But at a large scale, and used by a company, it may be easy for Apple to detect.
And don’t be fooled: the system worked by stealing someone else’s legitimate device ID, and pose as it to send messages to the system. So, this company could be making money by using you Apple device ID. I’m not ok with that.
I was under the impression that interaction with Apple’s servers required some kind of “proof” (honor system really) that you’re using an Apple device, which used device ID that was spoofed; just like how Hackintosh had done for push notifications for years.
Worth noting that Hackintosh got to a point where someone wrote scripts to generate random strings to brute force until they encounter a valid device ID, so they’d literally assume someone else’s legitimate device to get push notifications.
