Apparently they do.
Do people expect that, for example, future iterations of DirectX will support Win32 indefinitely?
I didn't even know about that notification. It's amazing how Microsoft are already back into their old patterns and yet people think it's "paranoid" to extend that to their future plans.
As owner of the OS it's a misuse of the notification system. It may or may not be true this week, but that really doesn't matter. They can run all the full page ads or sponsored content in magazines and websites that they like, or even run a huge banner ad when you start up Windows 10.
Should Google also be allowed to hook into Windows services to spy on what other apps are doing (Edge crashes 50% more often than other leading browsers, why not use Chrome?). But then they're not in a position where their competing browser automatically comes installed with the OS. We've pretty much been through this before, when Microsoft decided it was time to cut off Netscape's air supply. They've only recently come out from under anti-trust supervision for that one, yet already seem to falling back to old patterns of behaviour.
Don't be so paranoid!
This is literally happening on my PC right now.
Had all my video/audio associations set to Media Player Classic, but then all of a sudden everything got switched to MS's Groove player.
MPC wouldn't even show up when setting default apps; I had to completely uninstall and reinstall the software.
MS is shady as fuck.
The problem is also that we cannot seem to distinguish the MS of Xbox and the MS of Windows and Office here so any comment about the latter must be console warrior nonsense against a company with history of anticompetitive behaviour and found guilty of abuse of monopoly and market manipulation before.
Would MS like to have the Apple App Store model? Yes. Does that go throughout go progressively tightening the OS? Yes.
