The problem in opt in telemetry is it’s basically useless and is about the same as doing a poll, it over-represents a tiny minority of all users
This explains it better than I can: https://theevilskeleton.gitlab.io/2023/07/16/opt-in-telemetry-and-asking-users-for-feedback-may-not-work-in-practice.html
I think it could maybe be enabled by default in Windows now? Not sure as I haven’t used windows in quite some time and when I did I had it enabled manually so maybe it’s default now
