Yes, per @fhars, “fmi” is pretty common text-speak for “for more info” (which google will tell you if you search for it).

“Morally equivalent” is a term used in the classical hacker community to mean something like “essentially the same as, although not technically Computationally equivalent”. (And, as I noted below, it is also a standard, if a bit obscure, English phrase: https://simple.m.wikipedia.org/wiki/Moral_equivalence)
