I find it kind of funny that the last time a partial member list leaked (a few years ago) it was because they tried to invite Andrew Gelman and he mocked it on his blog: https://statmodeling.stat.columbia.edu/2022/02/16/hey-i-got-... I guess he didn't get invited again.
The posted attendee list has a top 5 HN user present.
Rust pusher too, lol.
