Not that guy but another: No. You? Because Microsoft is a lot of things but walled gardens is something out of Cupertino. Not Redmond.

You can call MS shitty and I would fully concur but a walled gardens it’s not.

You don’t need ad, Exchange/outlook, m365, entraid. They’re nice for most users but you can live without and use other services in their place on any MS platform.

Now, iOS… Have fun with that.
