VideoLAN @videolan App Stores were a mistake. Currently, we cannot update VLC on Windows Store, and we cannot update VLC on Android Play Store, without reducing security or dropping a lot of users… For now, iOS App Store still allows us to ship for iOS9, but until when?
No, the point of the windows store is that Microsoft gets more control over your machine.
Code downloaded from websites can still be (and is) signed; when it’s not you get that box where you have to click “Run Anyway”
