Your idea that Apple are incentivized to make people's phone experience as good as possible sounds like a wishful proposition. There's plenty of examples of Apple features and restriction designed as eco-system lock-in, behavior manipulation, or control limiting for commercial reasons. "What's good for Apple is good for our customers" is what they want you to believe, but as a long time iOS device owner, I reject that on numerous grounds.
There's also an equivalence flaw in your argument that sounds like it's coming straight from infowars.com: "the government is incentivized to put as many people in jail as possible".
I'm with your on incentives though. And one thing Apple have no commercial interest or incentive for, is fighting crime.
We don't live in Star Wars. There's more than dark vs light. My position doesn't mean I am not aware of western government corruption, bungling, even war crimes. But I am not permanently polarized, forever holding "the government" in contempt for misguided actions and evil intentions.
On history... if we're talking tyrannical governments, then "protection of user data" I suggest would not have stopped any given government in your examples from unleashing hell on its people one way or another.
