Hrm. People aren't reading the article that was in the OP. I think after reading the article, I'd have to say that 4th Edition does hinder options in character creation, but that a good roleplayer can work around the limited options and portray the character that they want.
However, I'll certainly grant the article in the OP that some people really don't want to be restricted in their character options.
Indeed, from my understanding WotC wants character options to be limited so that you'll buy the PHB II and the PHB III. If you already have all of the options with just the regular PHB I, then their business plan has already sunk.
But then I'd also have to say that just about any game system limits your options. That's because any RPG system you have establishes parameters and attempts to establish some sort of level of "fair play".
Those parameters and fairness in the game limits story and character possibilities. If you play 3rd Edition and all of the characters start at level 1, then you'll never have a party that becomes like the Fellowship of the Ring, because everyone will be the same level. Unlike the Fellowship, where obviously the characters had varying levels of experience.
I think 4th Edition limited character options in exchange for ensured character equality. That might be a mighty turn-on for some, but a big turn-off for others.
