He was more mad at the app developers for not putting effort into mzking the android port appropriate for android. And the fact that they don’t bother providing common needed functions for android apps. Like configurable settings.
Im not an expert on either as I tend to be a linux pc developer.
But user accounts is the way linux handles a program having its own space. Andriod has def made a choice from the begging not to have, and now to limit. The multi user part of linux. Assigning a user and group account to programs. Works great as a way of limiting programs ability to interfere with files of other programs without su access to allow the approval of only assess to those approved.
So I agree android makes a bad choice to ignore any extra protection.
