One of the hardest problems you can face is getting a community of disparate developers to do the right thing at scale; sometimes the easiest solution for that is a monolithic integrated blob.
I agree, that's why I applaud smart regulation. Apple is a disparate business too, you have no way to bring them to the table for doing "the right thing" unless there's some threat of repercussions.
It's really easy for Apple to back themselves into a vulnerable corner with the "ecosystem" mentality drawn out to it's logical extremes. I'd argue it's our democratic duty to stop businesses from endangering their customers like that, but that really depends on how you feel about consumer protections.
