"our data gave us confidence that device would have a great update experience"
Well considering the vast quantities of telemetry you've been hoovering up over the past few years Microsoft, it appears that you may well have been using the wrong dataset to make that decision.
And I personally would never associate the word 'great' with any form of experience related to Windows since you released version 8.
And FFS stop calling everything a device. A phone or tablet are devices; a computer/laptop/server are most definitely not. Those are tools used by people to do proper stuff and should be treated with a lot more consideration and thought when you are cobbling together your next OS 'update'.
