It starts off with facts but then just goes off the rails about middle gray and response curves. Both are just about perfectly linear in response. Middle gray is completely arbitrary on digital, unlike film. In fact, if you expose-to-the-right, there is no correct middle gray ever. The only difference between CCD and CMOS as a technology is in readout, which affects noise (CCDs are much noisier). It doesn't change the look at all.
