Are you sure that's not against the law?
Putting non-open files in/opt/chromium-browser/PepperFlash/ seems worse to me than putting open source files from f15 in /opt/google/chrome/lib which Jim Perrin (on 27 Oct 2013 @19:24 zulu in this list) said should be a criminal offense.
e.g. as a result of wget http://chrome.richardlloyd.org.uk/install_chrome.sh chmod u+x install_chrome.sh ./install_chrome.sh
