He has it exactly backwards.
The moral message of the movie lies beneath the superficialities of presentation, in the fundamental traits of its characters. Given their complaints about the false choice presented in this movie, one would expect objectivists to remain neutral in judging it on moral grounds. But, disturbingly, they are not. It's disturbing because, in a choice between a self-made innovator and a hero with innate powers, they side with the "hero". Instead of praising the American spirit of pulling yourself up by your bootstraps, they engage in royalty- and god-worship.
The "Self-Made innovator" wants to use the machinery to make everything Egalitarian, not what Rand proposed. The Heroes are the can-do's and the evil little troll is the government bureaucrat....FCOL. Even my 6 year old got that.
You're right. The author has it way-wrong. Syndrome's plan was not to make super-powers egalitarian. His plan was to use his technology to kill all others with super-powers, leaving only himself with power.
