> Just creating a tenant is a PITA and you get a default tenant you can't change without paying for Microsoft 365?

What exactly ist a PITA when creating a tenant? It's straightforward.

And what do you mean by default tenant that you cannot change unless you pay? Nothing comes to mind where that would be the case.

Are you sure you're not just using it wrong?

You literally cannot change your tenant ID and the form by default picks a random for you. There is a hidden form I found on reddit that lets you pick a tenant ID but wtf. Also by default you can't create a tenant without an existing Microsoft account, which everybody acknowledge is a chicken and egg problem.
