Chainlink does not solve the oracle problem. In the best case, they put a "price" on fabricating truth in the blockchain world.

If the "source of truth" is distributed, what stops somebody from running a worldwide botnet which pretends to be "anonymous chainlink nodes/contributors" and feed false information to the blockchain? Even if there is a price for each node to participate in the consensus mechanism, then you just set up a price which is required before you are allowed to defraud the oracle. How much are you willing to bet on this possibly defraudable oracle?
