You clearly have forgotten what installing software was like for normal people before iPhone, or maybe you weren’t alive/old enough for it. Apple’s approach to apps and the App Store ABSOLUTELY created massive values to developers.
I’ll quote Steve Sinofski (who literally ran Windows, so not a die-hard Apple fan), who said it well better than I ever could:
I was around for all of this and all I have to say is that when Apple is making Sinofsky look like the good guy, they need to take a long hard look at their life choices.
I come from Windows and around those parts he is not remembered fondly. He is largely responsible for essentially ruining the Windows that people of my time and place knew and more or less loved (to hate).
Perhaps it is not coincidental that the Mac is starting to suffer some of the same problems that he inflicted upon Windows.
