There is 0 opt-out telemetry in most (all?) major flavors of Linux. But there's an even more important issue here. Even if there were some form of telemetry in Linux you'd be able to see exactly what it's collecting and where it's sending it since the OS itself is open source. I do not think many people are mostly okayish with purely diagnostic telemetry, but it's not clear exactly what Microsoft is collecting and their transition to a sort of 'free to play' style of OS does not lead one to the most optimistic views for either the type data they're harvesting, or their intended use for such data.
