It's just the way larger corporations love to put smaller players out of business, sue them (unsuccessfully even) into submission and they have no money left.
Sony Europe did it to a import game retailer liksang.com, they never won anything, but just kept on sueing them until they went out of business, since sony europe just loooooooves to pricefix. they even made it illegal to import any psp or ps3 games/consoles and many online retailers are just afraid to even do it, because sony will put them out of business too.
