Of course, people who modify their settings in the first place are more likely to disable telemetry, particularly if they're choosing a non-default, low market-share application that specifically bills itself as privacy friendly.
If I recall correctly, that was their justification for no longer supporting it: too few people used it. Except it was tucked away in a small dropdown at the bottom of the customize toolbar screen, which requires right-clicking the toolbar to get to. If it was in the actual settings somewhere or, better yet, given as an option during the first launch flow, I imagine more people would've used it.
I didn't even know about it until after it became unsupported.
