The competition comes in, I think, when FIRST put out the RFP for the new control system - companies had a chance to come in, show off what they had for everything (including speed controllers, if I remember correctly) and get themselves chosen to supply things for the next few years.
Yep - the control system is singled sourced. That makes perfect sense from a complexity and safety standpoint - those components work together in a number of ways.

A PWM driven speed controller is stand-alone enough that competition can still be created though. The rest of the control system, not so much, except possibly the VRM.
