"Honest-but-rational or ideologically motivated validators could use this attack to increase their profits or stall the protocol, threatening incentive alignment and security of PoS Ethereum. The attack can also lead to destabilization of consensus from congestion in vote processing." Hey! I'm just completing a readthrough of this fantastic paper on some pretty serious attack vectors on PoS Ethereum for my podcast [Ethereum Audible](https://open.spotify.com/show/2QFr1GJjynogvNhidkoFl4?si=5edbd808f24a4395), I'm looking for any articles, responses or research that's out there rebutting it. Thanks! Link to the original paper "Three attacks on Proof of Stake Ethereum": https://arxiv.org/pdf/2110.10086.pdf
