Is his face that famous? Especially if he lost a bit of weight? Seems like it would be very easy to setup a new identity that'll pass any checks done by potential spouses and he's unlikeky to be recognized by most people. If anyone says he looks like that Minecraft guy, give them a strange look and a "I wish" or a "hah, my nephew said the same thing".
The strangest thing about the whole thing is that Mojang employees got rather little. If you were out with workmates and found a $2500 lottery ticket, it might be seen odd to say "here's 23 cents". Sure, the scale and absolute values make it different. Why not bring those folks along for a ride? If they could stand your code and they all got along well enough to make games together...
