Why would I want to get my apps from one place (Windows app store)? I don't even like buying my beer and spirits from our local government-owned monopoly.
I don't even trust Microsoft, so why would I continue to go back to Microsoft for apps?
There is only one thing I want from Microsoft, a great-looking, well-running, secure OS. I don't want to go back to Microsoft for anything else. I hate Microsoft overall. I use Microsoft Windows because I can't find the same software I need on Linux, and my hatred for Microsoft is shadowed only by my hatred for Apple.
