Opens the door for Microsoft to consolidate and make Apple look spread disorganized.
No it doesn't.
Microsoft isn't going to create a Netflix app that will let you stream Netflix content. Netflix will create their app for access to their content on Windows platforms and it will work the way that Netflix wants it. That is, their streaming app will be for streaming their content -- that's up to Netflix, not Apple, not Microsoft, etc. So, not a good example.
(As an aside, Netflix chose a long time ago to not let users manage their disc queues via mobile apps and there's nothing Apple or Microsoft can do about it -- they don't get to play there).
If you have have issues with a way an app works, you need to take it up with the developer of said app, not the platform provider.
Normally suggested upgrades are good for the OS. One would not "man up" and stay with old OS versions one likes, right?
I'm not sure what you're trying to say here and even less certain how it pertains to apps, who is responsible for them, and who actually controls them.--
