Yoshi-P: Flippant dismissal of player criticism is a poor look for a lead developer.

EEEEEEGHHHH WRONG

It's because of constant disappointment, feeling abandoned and then antagonized (by judgy people like you, actually), and, most importantly, due to their investment (both in a monetary sense and time sense) in this game.
You should probably give more thought to why people complain about anything, in general, before you start claiming that they lack fortitude after trying to antagonize them into leaving the game and seeing them persist.

I worked in retail for 7 years.

People will literally complain the price is as advertised. Please.
