Other than the part about tons of money, basically nothing you just said is actually true.
I also think you’re conflating the person, Markus “Notch” Persson, with the company, Mojang. By the time Microsoft bought Mojang, and Minecraft, Notch had already left any kind of development role on Minecraft years before.
Notch himself has made several small indie games after Minecraft, none of which were successes. Mojang also made another game after Minecraft, Scrolls (now “Caller’s Bane,” after they got sued by Bethesda over the name). It was also not a success. So much for “not creating anything since.”
They’ve also made Minecraft Dungeons and Minecraft Legends. Both of which were meh successes.
But honestly when you’ve got a cash cow eternity game like Minecraft, why TF would you need to make anything else?
