Diebold Denounces New HBO Voting Documentary

HBO is airing a new documentary called "Hacking Democracy" this Thursday at 9 p.m. about voting machine problems. (I didn't get a review copy so I haven't seen it.) Diebold demanded HBO include a disclaimer before, during and after the program, insisting it's filled with errors. Why didn't they just demand it not be shown? HBO has refused and the program airs tomorrow.
