He's done far more harm as a so-called "martyr for science", you mean.
All that his alleged martyrdom has accomplished is to cast one of the less anti-science church as this great enemy of science (and giving a free pass to the actual science haters), while allowing all the scientific quacks and loonie-bin theorists to say "Well, the establishment said Galileo was wrong, too!" to defend their pet theory.
I fail to see much positive in there.
