I took the time to read through Microsoft's documentation on data collection. I did it in several sessions because it was lengthy and boring.
I've also taken the time to read Apple's (equally boring).
I've also taken the time to proxy iPad and Windows to eavesdrop on their network activity.
My take away is as follows:
- Both companies collect a VAST amount of data. Seriously, a LOT.
- Microsoft documents WAY more about what it does than Apple. With some of Apple's products and/or services, I was unable to find any documentation.
- Apple claims to not associate much ("much" being the key word here) of the data with users. In many cases we have to take them at their word. (Keeping in mind (as their statement in this article attests) all network requests have an associated IP address which could easily be linked to one (or a handful) or users.)
- Microsoft confirms it associates data with users.
- Microsoft thoroughly documents how to disable analytics. (They have entire sections of their web site for this express purpose.) It is tedious, but doable.
- Apple only lets you disable some of the analytics. The rest you have to trust they're not associating with you.
At the end of the day, I trust absolutely no one. But using the Internet is already a compromise of one's privacy so you sort of just have to accept that. I think it's best if people have a balanced perspective and recognize that data is being collected by these companies and if you value privacy you need to do a lot of reading to understand what settings to turn on or off to minimize what data is transmitted.
