We have one person (this article) claiming this, and others claiming RMS put it there. I'm not sure who to believe, but given the other allegations, it doesn't seem out of character.

But ok, let's assume for a second that the article is telling the truth, and that someone put that there to mess with RMS, and it was promptly taken down, unfortunately too late to prevent a photo getting taken.

So what? How does that invalidate all the other bad stuff RMS has done?
