I wish they were lying about it, but they really believe it. It's why tutorials are overwrought and intrusive, mechanics are simplified, and consequences are minimized. It's the same dynamic you see with urbanites, where they believe that anyone that doesn't live like they do are not only morally inferior, but are retarded and "vote against their interests." In the case of game devs, they think anyone that didn't get a bullshit design degree doesn't know how games work, so it's on them to create the experience they think you should have because you can't possibly know what you want. Modern game devs, as a group, are midwits.
