That wasn't the only show they filmed though.
He could do nothing else when some of his guys refused to work with him due to his temper issues & forgetfulness to pay wages (allegedly). So CP employed those guys & they filmed it themselves....business as usual,but without Nev storming around in the background.
You could well be right about why they wouldn't work for him - but i honestly doubt he tried. They filmed very little else, as that wasnt what the company was set up for. Its standard practice that the team behind a show would stay with it - when Simon Cowell started X-Factor the Pop Idol team moved too. I'm not saying he cant be a bit of a Muppet, and as for Kerry, ugh.
