If anyone needs to get sued it's Ubisoft for how they treat PC gamers.
There is them to. As I have not been able to connect to their Fc3 servers for my extra content. I could say HM&M for Server connections dropping out. Which does cause frustration as it needed online connection.
Suing the companies on the grounds that they make a crappy or unfinished product will not solve the problem because if you sue based upon those reasons you have no legal legs to stand on and the suit will be dismissed. The software companies have lawyers and they know that a suit based upon the idea that their product is crappy will go nowhere in any U.S. court. The only real way to sue the companies is if you can prove that they violated the SEC regulations. I suppose you might be able to have some sort of grounds to stand on if you could prove that the companies acted maliciously and with intent to deceive but that's still a fairly weak case.
Whether we like it or not, the companies have a right to put out whatever quality product they want...whether anyone actually buys it is a different story.
Frivolous lawsuits (like the one in the linked article imo), are a big reason why our economy is so screwed up and cause nothing but a headache for the country and economy as a whole. You'd be surprised how far the power of the dollar will go and how quickly it will cause a company to change. The problem is that the consumers still buy the crappy products and so the company figures why should they spend extra money on fixing bugs when the public purchases/pre-orders the product anyways.
