Re: more needed than ever
Yes and no.
Most of Microsoft's "Spying" is feature analytics to allow then to improve their product. Google and Apple know so much more about what parts of the system their users use an how they use them than Microsoft does simply because of the huge amounts of information that they're siphoning up. It's very difficult for them to compete without that information.
Beyond that, aside from the fact that you're used to spying on mobile, there's really no functional difference. Most of what Google and Apple grab from you aren't necessary to deliver a mobile platform any more than they're necessary to deliver a desktop platform. You're not comparing apples and doctors at all. You're comparing an invasion of your privacy that you've become accustomed to and one you haven't, no more, no less.
