There are traders A and B in addition to yourself. A is as fast as you, B is slower.
How does it help you to slow yourself and C down? That just means A will beat both of you.

The thing is, you know to ignore the burst on the public feed, since you know it is coming (you created it). You still have to process the order book updates, but you can skip your decision logic. So any participant who has an internal latency (packet decode + orderbook update + decision logic) greater than 1 exchange cycle, and who doesn't have an "out" clause to stop making decisions if it is falling behind, will be vulnerable.
Like I said, I don't buy it, but it is possible in theory.
Also, "know to ignore the burst" doesn't mean you don't have to process it. It merely means you need to subtract the result of the burst from your signals.
