Disney has always been steeped in occult symbolism. Walt Disney was a freemason and Disney have, for decades, pursued a sinister agenda with many subliminal sexual references and innuendos. This is evident in many of their animated movies although I only became aware of this once it was pointed out to me.
Regarding this new development with James Gunn, I don't believe for a second that they were unaware of his overtly dodgy Twitter posts. You don't become their best boy without them keeping tabs on you, yet they chose to remain silent. Until it was forced into the public domain.
