Yet another thing that's impossible to discuss without being strawmanned by both sides. I'm not a hardcore gamer and for the most part play on medium or just slightly above medium difficulty in most video games.
I don't think a dev should have to accommodate customers that they don't want to accommodate, and this goes beyond difficulty. Souls games don't need a difficulty choice in the same way that Firewatch doesn't. Gacha games don't need to improve the f2p experience because those are games for whales.
It's like asking for sex drugs and rock&roll in disney movies and pg 13 horror movies.
