They can not make mcpe for free, because you have to pay a certain amount of money each month for your apps to stay up on the app store and Google play store.

So, this is how mcpe stays up. App that are free like Clash of Clans simply run off of in-app purchases, and apps like Flappy Bird run off of Ad Revenue.
