Ah yes. I have to explain this again. It’s that time of the week again. Android will never be free. Initially, android is harder to make. Secondly, the money is used to prevent the minors from downloading the game. You see, android is very common among the minors, so if there were no payment, they would be able to download the game freely, which goes against of the age restriction. (For real, people ask this at least twice a week)
