Read it again, it doesn't say that. It's saying that was the reasoning of lower courts, but for some reason the Supreme Court wants to take another look. They could've just accepted the Ninth Circus decision and that would be the end of it.
Edit: I bet if you polled legal experts before the corporate free speech decision, most would have said the court would rule against the corporations. Btw, it's interesting that the people who were against corporate free speech are probably the same people who say games are protected free speech. But aren't games made and sold by corporations?
A couple things:
One, there's actually a line in that article you apparently missed where it's suggested that the court may have accepted the case in order to simply but this to rest totally (as the other legal battles along these lines have cost various states 2 million put together).
Two, I don't really know what the hell you're talking about polling the experts about
Three, Who said I'm against free speech for anything? Now, corporations are allowed free speech, but using money is not a speaking action if that's what you're getting at. Also with the "aren't games sold by corporations" idiocy, SO ARE BOOKS, MUSIC, MOVIES, AND ANY OTHER MEDIA YOU CAN THINK OF! All those media are also protected by free speech so go figure numbskull.
