On Wikipedia's accreditation of the invention of binary code

The first binary code was Francis Bacon's bi-literal cipher, invented while he was just seventeen or so, staying with the English embassy in France. It was a means of sending secret messages back home, it's unquestionably the first base 2 code. "A" being aaaaa, "B" being aaaab, etc. But Wikipedia wants to credit Leibniz, almost a century later. Why is this? Could have something to do with the fact that Bacon wrote Shakespeare, if that ever gets out, it will be the end of the Yids and the Muslims, and also very embarrassing for the English. Who knows.
