The co-founder of Pink Floyd, Roger Waters, offered some harsh words for Facebook’s CEO Mark Zuckerberg after a request to use one of the band’s song to promote Instagram, which is owned by Facebook.

The story: The Pink Floyd co-founder said he received a “huge” offer from Facebook to use the 1979 classic “Another Brick in the Wall, Part 2” in an ad for Instagram. Waters said he rejected the offer and continued to slam Zuckerberg.
