I think one of the issues is the maintainer of an open source project will always have the final say in which patches are accepted. So the best way to not have any telemetry would be to fork the project and remove the offending code. Also historically, is /var/log any different from telemetry? I can easily figure out which applications were installed, what the hardware on the system is, which cron jobs were executed etc.
But in any case I agree that MS should definitely allow the owner of the machine the ability to block the transmission of any and all telemetry data.
