How is it possible that the author here is spouting openness here yet creates his blog on a white background with grey font color???

He complains that that there isn't some sort of open SLES (which there is, it's called openSUSE... duh!) But plays a double standard by intentionally excluding readers who have visual impairments/blindness with his childish choice of layout.

If you want to encourage others to be more open with their products, start with yourself first. Make your blogs readable by EVERYONE!
