Bigg Boss 10: Om Swami safe for 2 weeks now, is the show biased?

Monday's episode will see a new nomination process for all the contestants. Adding another twist to the nominations process, Bigg Boss calls Om Swami in the confession room and gives him a golden chance to win immunity. 

But in order to get it, he will be required to pay a certain amount which will eventually get deducted from the prize money. Without giving it a second thought, Swami agrees to all the conditions and grabs two weeks immunity. 

However, he is oblivious to the fact that the housemates are watching this entire process through JIO TV and are extremely upset with his decision. All hell breaks loose after Bigg Boss announces Swami Om safe from nominations as the housemates spare no mercy and lash out at him.

Now our question is very simple. After everything that Om Swami is doing inside the house and even after getting thrashed by host Salman Khan, why are the makers voluntarily saving him from evictions and nominations? Is the show proving to be rigged now? We would like to have an answer from the makers.
