I'm not sure why he or the talk is considered infamous. (Full version here: http://vimeo.com/22053820) When a client orders work to be done, that work should be billed as agreed and then the client should pay for the work they ordered. In design and web development, there seems to be some moral confusion among some clients whether they actually have to pay for the work the ordered. The speaker argues, and I believe rightly so, that this is bullshit.
