Look, you asked why. Some games aren't for everyone. I say the same thing about games designed for children not needing a prepare to die mode. FS games have an intended audience. That audience is more the "hard-core" crowd. I think, for example, there are very few people who would say colorblind options or hearing impared options are a bad thing within reason for most games. Difficulty is an entirely different issue. Especially when people have beaten these games with banana peels.
