Surely he sees the irony in it?
Gavin Hood, the director of Tsotsi, is pissed off that the tsotsis (*) are selling pirated DVD copies of the film.
I'm full of admiration for what he's achieved with the film but, by all accounts, his Oscar acceptance speech was a bit cringe-worthy. The sort of performance often associated with those lacking in a sense of humour.
Perhaps he doesn't see the irony in it after all.
(*) a Sesotho word for a thug or robber that refers to an urban thug
