I complained.
(back in the day)
I think that, while the technologies are not identical, it's clear who's pioneering them and who is doing ripping off.
Note: This is mostly for CONSOLES, I'm uncertain about the PC market, so if anyone can fact-check on PC controllers, let me know, but:
Nintendo created the D-Pad in a world of joysticks. Sega followed.
Nintendo created the shoulder buttons. Now we've learned to depend on them
Nintendo created the first analog sticks (for consoles). Everyone is following that to this day.
Nintendo created the force-feedback feature on consoles. Everyone followed (even when Sony didn't want to with its SIXAXIS).
Nintendo created the first appropriate motion controllers and games to match (as opposed to old peripherals like the U-Force which would just translate motion controls to button presses). Everyone else followed.
Nintendo has just released the first glasses-free 3D handheld. Now some smartphones are ripping off that same technology.
not to mention 1st 3-d console (though unused in GC) and first Console with online capability, The Famicon.
Look at the xbox 360 controller, now look at the GC Controller.
The only reason the Sony Playstation Exists is because of a rustle up with nintendo and sony, it was originally supposed to be a disk expansion to the super famicon
Move is Just a reverse engineered Wiimote
Avatars and PSN were brought to you by Miis.
SEGA was the only gaming compay that didn't rip off nintendo.... they were just 2 Gens ahead half the time....
I gotta hand it to Sony though, at least they copied only nintendo while Microsoft has that Failed overpriced unresponsive Eyetoy
