I am happy buying stuff from the iOS store. It's convenient, quick and easy. No objection as an end user.
Your views don't change even after learning that most of your purchases that are to support developers are being skimmed by 30% ? (similar situation to Steam but at least their development tools are nearly bug free, and really help development) The problem here is that they also charge 100 or $50 just to start developing on their platform...
Why would that matter in the slightest? If I'm a developer and I figure I need to make $4 off every sale, I just price my app at $6. It will make apps cost more to the end-user, of course; the end-user can then decide whether they want to pay in cash to Apple (via app purchases) to develop iOS, or pay in lack of privacy to Google to develop Android.
What makes me angry about this sort of post is that _right now I have a choice_ -- if I want to pay with money instead of privacy, I choose Apple; if I want to pay with privacy instead of money, I choose Android. Articles like this are clearly meant to _take away my choice_, leaving "pay by privacy" the only option available to me.
