Doesn't matter. Once Mojang devs burn out of making Minecraft, they will quit and move on to creative ventures, and once that happens, it's not Mojang anymore, and Microsoft will have created another husk of a company that they bought for billions.
The people who made id are pretty much all gone and they released a new DOOM game that's god damned amazing and worthy of being a DOOM game. Because id hired people who were passionate about their properties.
If the original Mojang team grow tired of Minecraft and all leave the company they will be replaced by people who are passionate about the game (which IMO is better than hypothetically having the original people there who don't give a shit anymore). Assuming they turn into a husk of a company not worth a shit is a very cynical perspective to have.
