minecraft also a large number of things going for it.

1. It was(is) a single game
2. It was already multiplatform, and only the most suicidal company would take a game that was multiplatform and make it exclusive. Not including the backlash as players lost access to a game they paid for, but there would also be untold number of refunds that would need to be done, lawsuits (most likely) to handle, etc.
3. It already had a very large (and most importantly) young userbase that they could monetize on dozens of platforms.
4. If you followed the proceedings of everything that is going on you'll have read that they actually wanted to make the new minecraft legends xbox exclusive. While the emails didn't say what ended up making them change their mind, I would imagine being in a certain legal fight might have played a large role in it.
5. Exceptions happen, but I imagine that exception would be the appropriate word rather than norm. But I'd love to be proven wrong.
