I think it's ment in the sense that power users are by far the most likely people to disable telemetry or "Send usage data to help improve this software" functions, if such a setting is offered.

Especially if the option is buried somewhere deep in the settings menu. Also the most likely users to have adblockers, though that's getting more and more common.

If it's a web app, you can't do that.

Depends. If you use a third-party, client side telemetrics provider it's probably on blocklists. If you track usage yourself on the server or integrated into your JS, then yes, you'll probably get good data.

if your user tracking is served from a 3rd-party domain, you won't see me or my family members in your stats. ublock, ghostery, requestpolicy. aggressive settings.
