It doesn't matter. If you have an OS that can update itself arbitrarily without your permission and you have a culture and legal agreements that allow uploading ambiguous amounts of data through telemetry systems, that OS is not a viable choice for anyone who takes security and privacy seriously and deals with potentially sensitive data. It's really as simple as that. My businesses have legal obligations under things like data protection legislation (for handling personal data) and our contracts with clients, suppliers, etc. (for handling trade secrets and other commercially sensitive information, as well as compliance with industry rules in areas like payment processing). Hand-wavy arguments about how everyone is using telemetry now do not relieve us of those obligations.
