I don't think Apple cares about the resource usage here. (Note that's not their argument, they argue that Beeper clients will bypass content protections.) The servers running iMessage, heck even the team supporting it, are probably a drop in the bucket for them. Apple's goal is for iMessage to remain an exclusive feature of their hardware. That exclusivity is what Beeper -- or an Apple-vended Android client, or RCS interoperability, or federation generally -- threatens. And -- it's exactly the proposition of, "to use our popular offering in market X, you must also purchase our offering in market Y" which is anticompetitive.
