It's the common denominator phenomena of all systems though. Mobile is literally the easiest point of entry to games and content in the entire world and it's not even close with all other platforms combined. The ENTIRE spectrum of intelligence and discipline have phones ("do you all not have phones?" -blizzard DI launch). It's in your pocket, it has all your information, access to your funds, and the majority of people probably get interrupted too frequently to scrutinize the quality of game design. It's a cigarette hit waiting for the bus kind of vice that the rest of the majority know that the game is garbage but just don't care- they need that dopamine hit.
