This tab was posted on Ultimate-Guitar, or somewhere else, a long time ago. I first discovered it there in 2005. I don't know if it is really him or not. But he says "So lots of respect for all you boys and girls out there who tab out songs like all the time. You bring rock and roll music closer to the people" (toward the bottom of the page). Perhaps he posted the tab himself on "Guitar Tab Universe", but he certainly did not say it in response to the MPA trying to shut down GTU.
