I think moral philosophers are often concerned with staying terminologically consistent with very old literature and distancing from many non-philosopher vegans' notion that the term "vegan" is permanently bound to one person's particular definition from one organization.
There is no "the definition" of veganism. There are, however, many people who love reciting one particular definition penned by Leslie Cross quite a while ago like a catechism, and who seem to consider faithful adherence to that definition more important than following the most reasonable ethical arguments where they lead.
Yeah and it's terribly confusing terminology.

Is that where the definition of vegan comes from, though? I've never heard that.
