Takeout is a terriffic service, but not a great way of doing this. It will actually create additional work. When you set up the new microsoft account you can simply migrate all calendars, contacts and mail as part of the setup. [1]

A lot of people are talking about entitlement and saying how people shouldn't complain when free stuff goes away. I think those people are missing the point. Google is an incredibly profitable company and it would cost them almost nothing to continue to offer this service. By choosing not to, they piss people off (rightly or wrongly) and won't make much of anything in return. We can speculate about how they got to a place where maintaining this service was painful enough to justify doing that, but from the outside it seems like a poor decision that is hostile to users and antithetical to how they used to do things. That plays into the narrative that this ain't your mamma's google any more and something cool about the 2000s spirit has passed away.
