Mojang, at least, was not founded by two guys who gave Microsoft the finger on their way out the door at their previous job.

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.”
Gabe seems to be able to handle wealth much better than notch, at least. If he would have been susceptible to falling off the deep end like notch, he would have already done so.
