THIS is the actual definition of Veganism, directly from the people who coined the term:
That definition is from 1988, so it’s questionable whether it came “directly from the people who coined the term” in 1944. Here is a re-publication of the 1951 Leslie Cross definition:
“The object of the Society shall be to end the exploitation of animals by man” and “The word veganism shall mean the doctrine that man should live without exploiting animals.”
Allegedly someone read The World Peace Diet (by Will Tuttle) to Donald Watson on his deathbed, and Donald Watson said that the book encompassed everything that he intended when he founded the Vegan Society. Make of that what you will.
Some do! Or at least, they give you a choice of OS at different price points. NovaCustom, Eurocom, and AVA Direct come to mind. Of course, there are also plenty of vendors that ONLY offer GNU/Linux pre-installed…
