Hrm, I don't know about that. It's questions like these where I wish I was a copyright lawyer. I think it's the same as above, though. First, that it depends what you're doing with the brand. Coka Cola probably wouldn't like it if you're defaming their product. Sure there's freedom of expression in the US, and there's also slander which I think a private company can go after someone. There probably other things too but I'm just guessing. I think also that with the tutorial, the person wasn't making a profit at all with it. It's probably the same situation for making a parody of something. Kinda like that New Voyages Star Trek thing that's getting popular. Fan based Star Trek episodes and stories, being legally distributed and those involved making no profit from it, artistically, so they are okay. Anyway, just wondering.

But about the right click? No, I don't know how to disable the right click (never did it before) (I assume you mean for a web site) but I do know how to enable it if it's been disabled ;-)
