Since Minecraft is one of the rare birds that you buy once and own forever (I paid $20 in 2011 while it was still in alpha beta, and I've been playing on that $20 ever since), it's outstanding that profits are still trending upwards.
Mojang could have moved to a subscription model, but they didn't. They could have stopped work on Minecraft years ago and charged $80 for Minecraft 2, but they didn't. Let us count our blessings.
"Hey, sailor chick, show me your boobs, heheh."
"Go away, you creep!"
"Heheh, she talked to me, heheh."
