He's still the villain. He sounds perfectly reasonable. His criticisms of Teldar paper are plausible. He makes a compelling case for greed, but by definition, greed is excessive, it cannot be good.

His apparent reasonableness obscures the fact that he's appealing to the rapacious or covetous nature of the shareholders. He wants to override any moral objection to the fact that he's buying the company, in part, to strip the overfunded employee pensions, and by accepting his offer, shareholders get a cut. (IIRC, it's been decades since I saw the movie.)
