Things like this are the reason I stopped contributing to Wikipedia. People with no knowledge or expertise are able to change facts at will, maliciously or otherwise. Someone once compared looking things up on Wikipedia to asking a question of ten random strangers at a bus stop. I think it's gotten much worse since then.
Have you stopped reading Wikipedia though? That seems like the real test. Who cares if you "contribute"? Is it your go-to source for random research or is it not? It is for me. If it's not for you, then what is?
"Things like this" are just evidence that encyclopedias are not reliable sources for items[1] involving controversy or interpretation. They never have been and they never will be. That's what analysis is for. The job of the encyclopedia, if it's done right, is just to document the existence of an argument and the lack of consensus (and in the modern world link to the relevant conflicting sources). And... it seems like Wikipedia did its job here?
[1] Like the apparrently apocryphal inspiration for The Human Stain -- honestly this seems like a genuine item of controversy here. Artists are not, in general, considered authoritative sources for their own works and for good reason. History is filled with great works where the author lied about them a little.
