Familiarity: I've used it several times
I have no idea why they say these only fit Shimano and Sram.
I have them on my Campy Chorus brakes and also my Dura Ace and they fit without issue.
And they are noticeably better than the yellow pads they replaced; they truly have better modulation, seem to have more power and are quieter on my Zipp wheels.
