Can we also talk about how this will enable FREE apps to simply distribute in the way that makes the most sense for the company/app without having to go through Apple's overbearing process.
It's not only about saving a couple points on each sale. There are numerous free apps that I would have done over the years for certain entities that would have worked if they could have distributed them on a website or specific customers, and not have everything go through the App Store. The developer account/app store itself is enough of a nightmare as far as "entity" is concern to discourage lots of types of development.
To one extent, this is useful to me and other academics. In my past 2 UK-based institutions, getting a dev account was out of the question. At my current Swedish institution, it is not impossible but not the easiest as Apple requires all sort of legal agreements (unlike other companies that verify your edu email). Due to this, for both research and education, I have been relying on Android.
