It wasn't so much the actual idea of the earth rotating around the sun that Galileo was punished for. It was more the fact that Galileo used analytical thinking to reach that conclusion rather than basing it on some respected Roman or Greek philosopher or the bible. If Galileo had determined that the earth rotated around the sun based on some scripture, there would likely have not been any trial. People might have thought him an idiot or disagreed with him, but they wouldn't have thought him a heretic.
The DMCA, or like in this article's "engineering" case, outlaws the whole act of thinking. Some areas are just off limit, no matter what you think, Sun rotates around the Earth or Earth around Sun.
