Since the article doesn't link to the study I will discard this as statistical meaninglessness.
How do you measure "10 times more"? If my OS steals my pictures but one converts them to *.webm before they get sent, and waste more MB data with that, did they collect more? Is an OS better because it sends more detailed location data but fewer times a day or the other way around? What if Users chat more on average on one OS? What about bloated apps that produce more noise? What about data that get's send but isn't sensitive, like I don't know, the average reaction time of the power button? You can send that 2000 times a day and I still care less than when you keylog me...
