The main issue raised several comments up is portability. No provider locks you to only using their email offering/cloud offerings if you register their domain through them. Even if they did, transferring domains is trivial and well-supported everywhere.
As far as any other objections people usually raise around using hosted email and the like, a domain really has no comparable privacy implications in the real world (you're not handing Google or Microsoft a huge corpus on your life). It's also through their enterprise offerings where as long as your bill is paid they're generally not going to have some automated review suspend your account with no reason, and if they did they have actual support you can get in touch with.
This solves basically all of the problems with using an @gmail.com/@outlook.com/etc email address.
