Indian Idol Voting Rigged by Sony

I sincerely think that the voting system of sony is not full proof.I think sony is manipulating the results to create more buzz and suspense.In addition to that by removing better singer they can encourage viewers to vote more for their favorities which in turn will lead to more revenue for sony.I just cant think India janta to be deaf when everyone around we meet are not happy with a single result.Or else may be a betting chakra is involved(though i am not very much convinced about this)
