Really hoping regulators crack down hard on Apple's clearly anticompetitive practices. If Apple allowed sideloading the entire point would be, of course, moot, but Apple's continued refusal to allow this is really the biggest problem, IMO.
I don't want a situation where 10 apps means 10 different privacy agreements. I also don't want to deal with app companies directly for returns or their custom payment solutions — an "Amazon" is way better.
