I get what you're saying, but nothing good comes out of mixing one silly agenda with another. And of course people will contradict themselves based on those agendas. Look at all the shit MS caught here when they were rumored to be making Xbone upgrades, and how far less slack Sony has caught.
The difference here is a Windows PC is an entirely different type of device in a completely different market. The PS4K is just a small upgrade to the PS4. You are, however, spot on about how people shouldn't make a fuss about one and not the other. The people coming in here trying to tell you you're wrong because a PS4K and PC are so completely different, are really just making the argument that Xbone games on PC are not nearly as big a deal as they were making it out to be.
