Yeah, but the point is that Sony might never have bothered with some of those things had Nintendo not popularized them first.
Also I'm not saying "copycat" as an insult. Nintendo has been a copycat in instances as well. I never denied that. I don't necessarily disagree with you completely either, I just think the particular argument you used ("let me dig up every really old and obscure piece of technology that mildly resembles something Nintendo did before Sony!") Is incredibly flawed, considering what the guy obviously meant.
Dual analogs and the standard modern control layout in general is the result of tons of copying back and forth. The original PS1 controller copied the SNES controller (as well as the Genesis controller's ergonomic grips, to a small degree), while adding extra shoulder buttons. A couple years later, Nintendo released the N64, featuring an analog controller and dedicated camera buttons. Sony responded with the original dualshock, which improved the analog and camera control concept by having two analogs (on a much better controller, I may add). This went on and on until this generation, where the Dualshock is now the essential template for all controllers today.
Tl;Dr Just because a fan of a particular brand gives any kind of observation or criticism about a competitor doesn't mean he/she is fanboy-ing.
