Also Windows configuration is terrible.
They market themself as standing for the open and free web and digital rights and privacy and what not. And then have the browser spying on every user by default with integrated ads.
So sure, you and me deactivate it, but a common person who just fell for the marketing and who does not even know what "telemetry" is, will have it enabled. The only reason I use their browser is, because there is no alternative - yet.
