But that would require the dreaded telemetry, which that subset of users care deeply about not having and would cry fowl if it even existed.

"Why the hell are you collecting information about what file system types I privately run OneDrive on M$!!"

Why, indeed.

Yeah it's impossible to get reliable statistics without using sleazy tactics to force every single one of your users into your spying 'telemetry' oh wait it isn't. Microsoft has a bazillion customers, their statistics will be fine if 99% of all users disable their spyware.

As far as I can tell, Microsoft told nobody. A blog post and an email to OneDrive users would have sufficed, neither of which use telemetry or happened.

Oof, no telemetry please. They know I'm a subscriber and have my email address.
