I don’t believe expected value is a new twist on utilitarianism. Utility is impossible to maximize under uncertainty unless you have a definition of utility that accounts for uncertainty. That’s why expected value has been a part of the canon of utilitarianism at least since Harsanyi’s 1955 “proof” of utilitarianism using expected value.

The other aspects that you point out seem to be pretty standard fare for movements/communities, because they work for achieving a collective goal. That seems not really to be part of a moral theory.
