Saying "jwz worked at Mozilla" totally understates his role in writing one of the original web browsers, Netscape Navigator, and his part in the creation of Mozilla.org, among other things. It's like saying Bill Gates worked at Microsoft, or that Larry Page and Sergey Brin worked at Google. Thus Brave supplanting Firefox could metaphorically be seen as Mr Eich supplanting jwz. (That's a huge "if", mind you)
