I think gamers in general are tired of Sony mocking a competitors product and then implementing that feature later on. They started doing this during the PS2 era. They mocked the inclusion of online play in the Dreamcast and then released the network adapter. They mocked MS for putting a hard drive in the original Xbox and then they released a hard drive for the PS2. While they would draw ire regardless, the fact that they openly make fun of an idea before ripping it off amplifies the hatred they receive.
