This gen is infested with games that look only to gather the largest amount of sales based on wide appeal, and are thus completely devoid of challenge even on their default difficulties and are transparently pandering. Demon's and Dark Souls were one of the very few that bucked the trend, and naturally, people want them to be exactly like the others. Because everything has be to the same, and every game has to appeal to everyone. Nothing can be niche; nothing can strive to be different. Nothing can be dead-set on rewarding skill, patience, and any sort of investment on the part of the player.
This is an entire generation of coddled gamers weaned on experience points that glitter the screen, achievement points for the simplest things, and other endless, superfluous forms of feedback targeted at tickling the pleasure centers in the most ham-fisted way imaginable. It's the equivalent of giving every kid a gold star so it doesn't impact their self-esteem. Something comes along that dares to be different - that dares to challenge - and people inevitably backlash against it.
There can be easy games. There should be. There should be games with various difficulty options. And guess what? There should also be games that forgo that, put everyone on the same level playing field, and create an environment where people share stories that everyone else can readily relate to. Some in the Dark Souls easy mode thread kept saying "options are good." Yeah, well, those are your options right there - the idea that not every single game out there has conform to the same absolute standard, and the option to pick the ones that personally appeal to you.
Options = variety in game design styles and philosophies. You have the ability to pick the game that's right for you, not to have everything under the sun conform to your own personal standard of what makes it worthwhile. Homogenizing is what truly reduces options, and the notion that everything must be absolutely accessible to every type of player is what has led to such a stark dumbing down of games in recent years.
