Are the corporations of WALL-E really all bad?

Cracked recently ran a scathing litany of 5 Terrible Life Lessons Hollywood Loves to Teach You. It is just painful to read because I can make no solid argument against what Cracked is saying; in particular what they have to say about the irony of casting corporations as villains:

Each and every one of these films are made by a corporation every bit as huge and unfeeling as the ones being portrayed in the movies (and the Walt Disney corporation could crush all of them like a grape). There’s almost something condescending about the way enormous companies are willing to cast themselves as the villains, knowing we’ll give them more of our money to watch it.

Corporations: the cause of, and solution to, all of life’s problems.Speaking of Disney, in the movie WALL-E the earth has been ruined by the excesses of humanity, fueled by a greedy, uncaring, ubiquitous corporation with the cute name of Buy ‘N Large. But here is the thing I don’t get: if Buy ‘N Large is the corporation that made everything, then they’re the same ones that created WALL-E, the robot who saved humanity, and they also made EVA, a robot tasked with finding plant life, a sign welcoming people back to earth — www.buynlarge.com even says they make robots. So wouldn’t this mean the big, bad corporation that caused this mess is also the one with a plan to solve it? Surely someone within Buy ‘N Large was looking out for people after all.

Sadly, I don’t think this was the message the movie intended.
