The part in the middle of the cut steak appears to be where a fork pierce was while cutting crossways with a knife. This will happen even to juicy steaks. Not sure if that's what you were talking about or not?

Internet isn't really "strange" it's more so that it gives any and everyone a voice. There's a lot of dumb people in the world and we're just a lot more aware of them bc of internet. Anyone with a negative opinion on this particular steak couldn't cook a steak properly I can almost guarantee.
