The difference between a flashlight application for WP7 or Ovi on the one hand and Google on the other is the amount of data they have about me... and the way Google collects it without telling me.
Governments wouldn't get these answers from any flashlight application (that I don't use anyway) or from a particular Ovi service that stores location info from pictures I took.
If that sounds paranoid to you because, well, there's nothing you'd have to hide and you're online profile is too mainstream to be of any interest: Yes, today. But what about tomorrow? Imagine you live in Egypt and a year ago, you'd have said: "Nothing I have to worry about, I'm a good citizen! Not only do I have no connections to the opposition, quite on the contrary, every trace I might leave online proves I'm an active supporter of Mubarak and his regime. Hey, records about me could even prove that I turned two activists of the opposition over to the secret service!" - Now. Fine. Times change. We're not so sure if this is true for your data that's stored by Google.
That chart shows that OS X plus Linux makes up about ten percent of the desktop PC world. That's a heck of a lot of people using Unix, and this is counting all the machines used to browse the web, not just the ones sold recently...
