I have zero proof of this so take it for the musing it is, but the Internet Archive/Wayback Machine can be used to view articles that have been taken offline (sometimes for political reasons). The IA is a very accessible way to prove that once something is on the Internet, it's out there forever. I used it in a recent post to show an Israeli newspaper article that argued Israel had a right to not just Palestine, but Lebanon, Syria, Iraq, and other territories. It was taken off the newspaper's website a few days later, but IA had it.

This may explain why no one is taking credit, and there are no demands. Or it could very well be another reason, including people just being assholes.
