He doesn't seem to realize they aren't American either.

I do, and it doesn't hurt the point in the article because the rant isn't directed at all the companies that are anti-consumer. It's directed at the bad example the US market sets for the entire world. It's the leading market, the richest country in the world.

In other words, if US companies didn't misbehave and US were still the largest market in the world, would other companies like Reason be bold enough to screw consumers?

Let's not be cynical here. What happens in the US ripples across the entire free world just because it's in a position of economical and political leadership that it carved for itself by means of force and influence since the great world wars.
