In case of Microsoft, this is a whole new dimension and not comparable to Mozilla. First Microsoft products are (usually) closed source. That alone is a black box and we don’t know what is sent, compared to open source Mozilla projects we can actually understand what is going on and report. Secondly, Microsoft does it not only with the browser, but on the entire operating system, if you want it or not. It’s not opt in, not opt out, its just selecting a few options to sent a few less data, that’s all. Which BTW reset themselves sometimes for unknown reasons.

Putting Mozilla and Microsoft in the same sentence about privacy and telemetry is heresy (towards Mozilla)!
