Crash reports are not telemetry, they are debugging/error reporting tools. Every application that has ever had a crash reporting function, did so by prompting the user to submit it first. The reason is pretty obvious: crash reports contain more data than a user might like to submit, and so the user gets to choose to submit it or not. Often they do choose to submit it, but again, they get the choice, and don't need to go through an awkward process to manually copy their offline data into an online process. Nobody has stopped using operating systems and browsers just because they have a crash reporter that can optionally submit the crash report to an internet site.

Telemetry is not sensitive data. Telemetry is "signals". For desktop software, telemetry is often what operating system, cpu architecture, and software version you're running. Your OS reports that, your browser reports that, every self-updating application you use reports that. This is not controversial nor sensitive data and has no privacy implication.
