^ Cool.
Mountain bike component designers come from various backgrounds and we are all the better for it.
BMX influences ushered in the A-head stem, platform pedals, low slanted toptubes etc. Motocross influences brought about disc brakes, the modern "dog leg" MTB brake lever shape, knobby tires, full-suspension, thru-axles, riser bars and so forth. Road brought in the passion for weight reduction, butted frame tubes and spokes, cassettes and derailleurs, hollow quick release axles, amongst other things... including the DC levers.
We're pretty spoiled for choices, and it's all there for us to pick and choose for our various applications, to enjoy as we please. It's all good.
