Allow me to be counter for a moment.

If I'm a developer, all of this snooping doesn't matter to me. I'd just use the platform to develop something, avoid Microsoft Edge unless I totally have to use it and be done with it.

As a consumer, it would bother me - all of the privacy concerns rolled up into the guise of "convenience". Cortana listening to my voice as well as snooping into my emails... well, I did need that reminder for that birthday I almost forgot and my travel plans next week.

As a business... Microsoft privacy concerns and actions would truly bother me. My IT department would have to capture, sample and list out all types of data going to Microsoft to settle my nerves. Would not want my trade secrets and other intellectual property become a target on not only my own servers and networks but also on Microsoft's too.

In the end, if it's avoidable - and to me it's wholly avoidable with the options we currently now have for personal computing - the uproar I'd pay attention to would be the arguments I've not considered yet.
