The big company isn't taking over, the big company is making the thing so they own it. The point was that having a similar distributed solution takes power away from the big company because it provides an option for users to choose if the big companies implementation becomes too onerous.
I thought the whole idea was it is "distributed" and non centralized. If big evil company takes over, can't you just fork? If it really was decentralized, why would i care about the direction the central commitee takes?
