Anyone who subscribes to the view that BB-like shows are edited to show what the producers/directors prefer should read Ben Elton's book 'Dead Famous'. He had this side of the show rumbled, and it was written as far back as between BB1 and BB2...
Although Ben Elton's an establishment product himself. No idea where he fits into the MTV/Endemol brainwashing business (if at all - and probably not) but he was certainly used himself to project a TV anti-establishment veneer in the 80s.
See also the staggeringly prophetic TV drama, "The Year Of The Sex Olympics" (which I believe is available in its entirety on YouTube) which was made 32 years before BB1 even existed.
