I'm also trying to figure out the reasons for this "holy war" about whether whether networks should be big or little endian https://www.rfc-editor.org/ien/ien137.txt
Was the motivation mostly that people didn't want their machines to pay the cost of byte order conversion? ("my platform is little endian, so if networks are little endian too, that will be better for me”)
again, I'd love references or links if possible, not speculation. I'm really struggling to find any archives of these discussions from 1980.
