There is a big difference between documentary type reality shows and the reality shows which are completely made up for TV like The Apprentice. A hobby group I am a member of didn't renew their agreement with Discovery for a yearly TV special because the show quit showing the real hobby and just made the show into idiots doing stupid stuff with the hobby. The hobby group had a lot of complaints from members about how it portrayed the hobby so the group didn't renew the contract.
Duck Dynasty was supposedly a documentary type reality show, but the producers admitted the show was basically scripted and had nothing to do with reality. The producers gave the cast a story idea for each episode that had nothing to do with running the business.
