Indeed, I wouldn't try to find a case for "good telemetry", it basically means snooping, as far as I'm concerned. And this is not even something that can't be replaced : if you want to know about your users habits, ask them. I would have no problem with seeing once in a while a broadcast message after syncing packages showing me an url of a poll. But automatic data collection is never ok.
