I don't want to defend Jimbo Wales (he's very touchy about the subject), but to be honest, even if he's a founder, Larry Sanger didn't contribute much to what Wikipedia today is.
If someone builds a free knowledge-repository platform and makes it available for worldwide use, and if that platform takes off to become commonly used globally, then I think some credit is due to such founder and innovator.
Larry Singer was essentially running Wikipedia in the early days though, until he was laid off, so in some sense we could think of him as a co-founder who was ousted. It's true that he didn't contribute much (as an unpaid volunteer) after that though.
