ESS defaults predated Hadley's contributions by a decade, making his seemingly unique adoption of snake case extremely unsociable. I actually use _ to <- a lot. It's enough of a pain in the ass, I basically stopped using his packages. This was annoying, but ultimately the Hadleyverse became a bridge too far for the kind of bread and butter data science I do, so it turned out to be helpful to me personally.
