AFAICT, the core of Melan's post is:
All in all, what we are seeing is the emergence of a philosophy that denies and stifles excellence while encouraging mediocrity and poor play. Attempting to "protect" gamers from their own mistakes will not result in better games - it will limit self-expression, the freedom of creativity and hinder the natural and easy learning process most of us have gone through. It will subtly, although of course not completely, shift roleplaying games towards more passive and consumption-oriented forms of entertainment. The roleplaying hobby will be poorer for it, and it can also be expected to experience slow and continuous shrinkage as it becomes apparent to people that passive and consumption-oriented forms of entertainment offer much better alternatives than sitting around a table and rolling polyhedral dice.
