Roger Waters of Pink Floyd claims that Mark Zuckerberg asked to use “Another Brick in the Wall” in a Facebook ad, according to Brooklynvegan. Speaking at an event in support of WikiLeaks founder Julian Assange, Waters described the proposal that arrived in the form of a letter from Zuckerberg himself. He says he turned down a “huge, huge amount of money” for rights to the song for an advertisement.

Waters pointed to the message of the song and criticized Facebook and Instagram for their massive power and censorship. “They want to use [“Another Brick in the Wall”] to make Facebook even bigger and more powerful than it already is, so it can censor all of us in the room and prevent this story about Julian Assange getting out.”

He says his answer to Zuckerberg was, “F*** you! No f***ing way… I will not be party to this bullshit, Zuckerberg.” You can watch the full video here. He also claims to have received the proposal the same day as the Julian Assange event. Perhaps Zuckerberg didn’t expect Waters to accept the deal, but meant to distract from the effort to free Julian Assange.

Waters recently made headlines after he released a note on his website announcing new stereo and 5.1 mixes of “Animals” and furthering his infamous feud with David Gilmour.
