I don't, but I can't speak for everybody else. In my case the telemetry was on the backend so the users had no say at all -- though my teams made sure for there to be zero personally identifiable information (plus our API endpoints never got even one piece of information about the customer's devices / desktop browsers; I code-reviewed those PRs and enforced it). Don't look for boogeymen on HN, they are not on this forum. ;) I'll again agree opt-out by default is not the most privacy-friendly approach but voluntary user surveys had almost non-existent user base. So some companies took a more aggressive approach. Those I don't like. But a Linux distro? Dunno, seems like an overreaction in this particular case.
