Same with RSA and other things, I think the author's point is that slapping your name on an algorithm is a pretty big move (since practically, you can only do it a few times max in your life before it would get too confusing), and so it's a gaudy thing to do, especially for something illegitimate.
The RSA authors didn’t name the algorithm after themselves.
Leonhard Euler has entered the chat: https://en.wikipedia.org/wiki/List_of_topics_named_after_Leo...
Nothing on that list has been named that way by Euler himself of course.
if you’re Euler you get a pass
