I can understand any company or individual not wanting a product that they are selling to be allowed for free under any circumstances, but most people accept it as inevitable and spend their energy trying to block the free versions from the most obvious places (like RapidShare which is free, popular, and easy to access but does have conditions for blocking downloads if the owner of the distributed material complains). However, you would think by now a company like Microsoft would learn that they are not going to create anything that can't be exploited.
