All of that interest is from people making computers, or people who manage security. Not from people that use computers as part of their life/work (in contrast to those who's work is entirely about the computer itself). From a usability standpoint, this type of sandboxing for every app is cumbersome and all it leads to is users finding unsafe work arounds. I used to be able to use my android phone much more as a regular computer than I can now. And I wanted to make a simple app for myself to allow me to automatically copy and catalog photos from my cameras sd card to an external HDD, and I literally cannot do this without jumping through a million permissions and API hoops on Android even though I never plan on publishing this app for others to use. It became such a pain to figure out how to get access to the folders I would need, I just gave up on the entire project. I essentially needed a tool to systematically copy and rename files, and it's nearly impossible because of these nonsensical policies.
