His writing is very different from what was published under the name of Shakespeare, that's why many reject him as the author. Edward de Vere is a more likely candidate. But Bacon does seem to be part of the project, encoding secret scientific knowledge in the plays and legend around Shakespeare. He seems to have taken over that role from John Dee after the latter died and Bacon became the head of Rosicrucianism. I don't know this, as I'm just going down this rabbit hole, but this is Alan Green's stance. Do check out the rest of his videos, he has great stuff.
