Not actually subscription based
That $13/mo is not for the game. That is for their easy setup they-host-the-server plan for you and your friends, called Minecraft Realms. You can also host a server yourself or pay another hosting provider to do it for you. The game itself is a one-time purchase whose price has been raised over the years as the game progressed, starting somewhere around $10 (iirc) and coming up to $27. It has remained that way for a long time. Once a person has bought the game, they have it and can use it on as many devices as they like. Nowhere near 12.8 million players use Realms (they havent relased any actual numbers, so this is only an educated guess.)
Their website says it's $13/mo subscription.
But how many subscribers, I can't find that.
By my calculation. 2.5B / $13 / 15mo = 12.8 million subscribers.
That seems feasible.
