It's kinda like an example of a high frequency trading strategy applied to a decentralized network. Basically you're betting on volume and speed over maximizing the value of each individual block. The logic is that if you're a big enough player those fractions of a second you save by not waiting for the mempool to fill up will over time add up to more total block rewards than the sum of all the fees you missed.

I see it as a game of probabilities and large numbers and for a pool with a significant percentage of the network hash rate it might be the only logical way to compete at the very top. But do you think this kind of incentive could ever become the dominant method for all pools even smaller ones?
