Well, that is the General Relativity (GR) view. This view says that gravity is the result of a distortion in spacetime. The Quantum Mechanical (QM) view is that gravity is the result of the interchange of gravitons. Gravitons of course are the force carrying particles of the gravitational force. This is just a difference in view point which will be resolved when a theory of quantum gravity is eventually developed. In the mean time it is a lot easier to count it as a force unless you need to do GR calculations. In any case I don't think it is anything like Finiter's view.

C is not the speed of light in a vacuum.
C is the universal speed limit.
