I'm sorry, but you're several years too late with this argument.

BW cameras and one one other case mentioned below) is the count

If you are using a red, blue, or green filter it effectively does.
Only it is a little worse for red and blue and better
Only if the filters are perfect, which they are not. The blue and green sensors will
see some red light, but at a much lower intensity than the red sensors. The Bayer
algorithm is to some degree able to use this data in building the image.

Not yet. The Foveon sensor in the Sigma XD-9 is only 3MP

Not even that. It's usually 1.5M

Wrong again.
And in any case we weren't discussing the way marketing

one colour component.

i do hope you are kidding.
they *do not* provide an output file of 2000X3000
pixels, each one being a 24 bit color, at least not in
the raw file format. canon's raw file is a (losslessly)
compressed 12 (or 10) bits of data, one color only, per
pixel. the rest is interpolated afterwards.

Yes, all green and blue sensors will be black, but I would argue that
this isn't actually a loss of data. If you look closely at the output
