I think it's a bit naïve to suggest that Apple weren't coming after the Hackintosh exploits for their own unrelated reasons to be honest, and they absolutely knew what they were.
Those exploits have existed for 10-15 years, they are as old as the hackintosh community.
There is a difference between commercial exploitation and hobbyist usage - just like with legacy emulation vs pirating. And no, apple really hasn’t come down despite knowing it exists, and probably wouldn’t have without beeper.
It's really not fair to say that the scene was "just fine" up until Beeper went commercial. In those 10-15 years, there were a lot of changes intended to segregate Hackintoshes from Macintoshes.

What damages would Apple claim? That people didn't buy iPhones to use their insular and potentially-illegal messaging service? That they abused the same resources that millions of unknowing users exploit for free daily?
It's Apple's call to pull the cord whenever they want, but it's also entirely their decision to keep iMessage a walled garden. It's impossible for you to redirect the vitriol towards Beeper when the only thing they did "wrong" was sell a solution to an Apple-designed problem.
They don't need to claim any damages, this is not a legal question, they can just close the loopholes.

No, the issue is not that they are "solving an Apple-designed problem" (whatever that problem may be), it's that they did it by leeching off of Apple's infrastructure.
Beeper's solution didn't overhelp themselves to Apple's infrastructure, though. They used iMessage like a legitimate user would, and then charged customers for the automation. If that's leeching, then thousands of iOS and Mac users around the world are also leeching off Apple's service too.
I won't contest that it's Apple's decision how to present iMessage. The idea that Beeper killed iMessage spoofing is a hysterical assertion though, when people will readily admit that it was Apple's double-standard keeping it alive in the first place.
