This interview from Gabe shows that he knows there is a problem with this, but he doesn't realize how bad it is:
Newell: A lot of times people will want to complain. The first time somebody complains, you say, “Okay, fix it.” You just say, “I don’t know what you expect to happen now, but you’ve just given yourself a job.”
Fries: Does that train them to complain less or to fix things more?
Newell: If you hired the right person, it trains them to fix stuff. If you hired the wrong person, they’ll say, “Oh, this is mean.”
