In more detail: http://en.wikipedia.org/wiki/Chroma_subsampling

The inherent assumption on which chroma sub-sampling is founded is that luminance information is far more important than chromanance information. This is backed up by empirical evidence. From there, the effect follows directly from the equation for luminance:

Y = 0.2126 R + 0.7152 G + 0.0722 B

From here you can see that green is by far the most important color, followed by red, and then finally, way down there, blue.

But is there a logical reason to not do it?

It goes against the grain of the web, that's why. Sites that connect so many users to so much content should not do that.
