I don't agree with the first article at all, a company deciding to sell items in game and items being bought and sold outside of the game are completely different. The second article was pretty good, the only thing I would like to add is that not everyone knows how to make money at a fair rate or train a skill as effectively as possible. That is why you might see one person with level 60 in agility, runecrafting, minning, and prayer, that plays just as much as another player that has, say 85 in the same skills.
