> hypocrisy of Apple's moral assumptions
Apple's 'moral assumption' is that Spotify would like to 'freeload' off of their store. The App Store is provided with the intent that services which are based off of it contribute back to the App Store.
Open-source software is not provided with the 'moral assumption' that users contribute back.
There is no hypocrisy here. Apple is criticizing Spotify for trying to sidestep the moral expectations of the App Store, but Apple itself is not sidestepping moral expectations of the open-source products it uses.
> Windows and GNU/Linux are doing fine.
Are they? In what context? Do you really think Windows does "fine" for the average user, and that they are not at a huge risk of malware, terrible software, and more?
It's also disingenuous to say that security problems are not in large part caused by how open available distribution channels are. We have proof showing that the App Store has provided an objectively more secure environment for the average user than Windows or even the repository model.
