You don't think there's a way to mitigate this sort of attack at all?
Just one method: You could use a weighted average price from multiple oracles that updates on some determined interval and rejects price changes that are too far outside of the weighted average.
You are describing a federated oracle system, and federated is not the same thing as decentralized. Oracles provide their service because they make an income doing it, and this income aligns the incentives of oracles to report as unified a price as possible. That incentive naturally aggregates them into a cooperative that controls the pricing mechanism of any system that relies on them.
