For sake of argument, if they acquire the Beeper team and continue supporting it, there is no further incentive for more Beeper-like apps to emerge.
Apple would at that point have a leg to stand on when they go after non-native apps, and I think this would actually be a deterrent for copycat attempts and not something that encourages the behavior.
If Apple wanted iMessage on Android they would have done it already. There are emails from executives made public in lawsuits discussing the possibility many years ago.
It’s very clear that Apple does not want iMessage on Android.
My point was that if they chose to give in and acquire something like Beeper (presumably due to bad press, concerns about regulatory action, etc), it does not follow that this incentivizes more Beeper-like products.
