It is something to always take into consideration and not forget.
Wondering how these magicians measure quality of service then, since they collect no juicy data. I find this hard to believe.
Quality of service is usually only useful with aggregate data which is worthless for prosecuting an individual.
That’s not true. We used to collect client and server data both to detect issues and even if it was only in a subset of customers there is just some customer facing QoS issues you wouldn’t find unless you were collecting data, that wouldn’t be found on server side for example. Like let’s say iPhones make an update and you’re doing video streaming, maybe certain video formats would lag when streaming to the player but not on an android or vice versa.
Aggregate data doesn’t mean no client side data. It’s possible they’re collecting aggregate level client data too. They could go further and collect data on individuals that is not identifiable or useful to law enforcement in any way. I can think of a few ways to get anonymous usage data that allows you to improve your service while protecting your users. I don’t know their scheme but they clearly don’t need overly invasive forms of analytics as they have a solid service.
