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

IMO it’s a bad thing if this doesn’t get added. FOSS in general has very limited resources, knowing what to work on most urgently will help massively to tackle the most urgent issues
