Roger Waters has never been a man to mince his words.

The Pink Floyd frontman has been very outspoken on various topics over the years, from politics to music. Now, he has taken a stance against none other than Facebook, calling its founder Mark Zuckerberg "one of the most powerful idiots in the world" and a "little prick".

The outburst stemmed from an email that Waters claimed he received from Zuckerberg, asking for permission to use Pink Floyd's 'Another Brick in the Wall Pt. 2' for a Facebook promotional film.

Speaking at a forum to support Wikileaks founder Julian Assange, he read the email aloud, which reportedly said that the Facebook team "feel that the core sentiment of this song is still so prevalent and so necessary today, which speaks to how timeless the work is”.

Waters said: "So it’s a missive from Mark Zuckerberg to me. Arrived this morning, with an offer of a huge, huge amount of money, and the answer is – fuck you! No fucking way!

“And I only mention that because it’s the insidious movement of them to take over absolutely everything. So those of us who do have any power - and I do have a little bit – in terms of control of the publishing of my songs I do anyway. So I will not be a party to this bullshit, Zuckerberg.”

He called Zuckerberg "one of the most powerful idiots in the world", referencing Facebook's beginnings as a 'Hot or Not' style website. "How did this little prick, who started off by saying, ‘She is pretty, we’ll give her a 4 out of 5,’ ‘She’s ugly, we’ll give her a 1’ – how the fuck did he get any power in anything?”
