With the examples you listed doesn't it require an account to authenticate first before achieving this?
Furthermore, is this not easy enough to spoof? Without account based authentication (which as far as I know Unity does not use/require?) what stops me from spinning up VMs or emulators repeatedly to attempt to install bomb?
Microsoft tells you if you install the game on too many devices.

Uhm, no, that's how it's implemented but it isn't required.

Nothing, but it would be very time consuming and very easy to detect.
It is a solution that can be done more, or less, correctly or fairly. But the problem is that it is easy to get it wrong, it is easy to implement this incorrectly.
Given how slipshod and slapdash these announcements and responses and walkbacks have been, you can't really have any faith that they will fall into the "right" side of things.
