No one is pretending Apple is a charity. Of course they do all this for obscene amounts of profit. But if we get stronger privacy as a side effect, I think that’s a generally okay situation.
Apple is almost too big to defeat. With the flip of a switch, they could turn course. (I would argue in many senses that they have.)
They're already obeying local governments as a central point of censorship and control. Even the FBI/NSA has them monitoring the files on your device.
Apple is too many functions wrapped up as a single legal entity. They have too much control, and they're growing bigger every year.
