Manufactured discontent is the only reason these games make money. They're not a charity. They goad you into wanting whatever costs money. You can say no, but they try their absolute damnedest to squeeze out a yes.
Success here is inseparable from wringing money out of players using any means necessary. Acting polite and gentle is just another tactic. You are still being manipulated.
There's no game that's just so gosh-darn enoyable that people freely throw four billion dollars at it, out of the goodness of their hearts. They get roped in and ground down. They brag about how many thousands of hours they've spent not being addicted. They insist they chose to buy the stuff that's shoved in their face on every load screen and round summary. Obviously they feel no obligation whatsoever toward mere cosmetics, but oh wow look how fancy that is, it super sucks you don't have one of those.
Like, I don't know what a "stash tab" is, but I bet if I look it up, it's gonna be added functionality that's objectively missing from the default version of the game, and that it costs the company approximately nothing. (Ugh, I shouldn't have actually looked it up. That whole page is gross.) You obviously want that. It is withheld from you. Maybe not exclusively for real money - but gosh, what a lot of grinding it'd take, if you don't fork over real money. Maybe just this once... right?
