Same with Netflix, and Hulu, and Prime, and Disney, and HBOgo, and on and on and on. As a user it’s on my shoulders to navigate all this complexity. Yuck!
This whole “single AppStore” thing is only a big problem to developers. That’s why it gets so much attention and air time here because only developers whine about it and we are all developers. As an end user I just want one app distribution system to worry about.
