Of course he can post as much as he wants where he wants. And in turn, people can call him out for his absurdities. Like trying to downplay the S6 (both camera-wise and other aspects of it in other threads/posts) despite having no personal experience with it, and then in this thread, making the excuse that the iPhone 6 has older hardware. Again, if he's going to use that argument and truly stand by it, there are plenty of questions to ponder, all of which I detail in my post to him here:

Have a read and tell me if I'm wrong. He doesn't seem to want to properly respond to it, which in itself is revealing.
