I understand your point (regarding protection of intellectual property and having a homogeneous and controlled IT infrastructure), but I'd like to add that as a business (disregarding what my employees might like or consider more effective) I am still not in control of anything if my data and applications are somewhere "in the cloud" and I have no control over it. As a company I would be bound to that provider (in this case Microsoft) and would have to pay whatever they require for whatever they offer(good or bad services). A small alleviation would be to have that "cloud" on premise, but I think that that's highly unrealistic. In this regard, a business is very similar to the plain user in my previous reply.
Also, don't forget that GDPR doesn't apply everywhere. That's just a EU requirement which might or might not be fully implemented, even when required. As I mentioned, there's no guarantee that your company data is not misused when it's completely out of your hands. Not even to think about what a security breach or outage would mean and what kind of impact it would have.
Please don't get me wrong. I'm not trying to spread FUD, but I am general skeptical and trying to think critically. Moving "everything" in "the cloud", in the hands of one single actor requires a level of trust which I'm not able to provide and introduces single points of failure which I wouldn't like to have, neither as individual nor as company.
Telemetry won't be a topic anymore under such circumstances because will be implicit and the least of your worries. Tracking the input of the users will be part of the service they are paying for.
a user can access all their applications and data from whatever client they are using
Also, users won't own their most basic data anymore, nor will they be able to control how it is used. Canceling a subscription (or being locked out) could mean loosing it all.

Thanks for reading my longest post ever. ;-)
