This is a shady and malicious move from marvel to blacklist james gunn
They used out of context tweets to justify marvel getting rid of james gunn.
The actual reason why he was fired is creative differences turned nasty. James gunn expected a similar arrangement to the first 2 where he got plenty of creative say. As it turned out, kevin feige wanted more creative control by increasing the number of villians and pointless sideplots.
When james refused, marvel then fired him. He went to disney to complain of kevin's ruthless tactics (being abusive to directors like james gunn, edgar wright, Joss whedon, and the Russo brothers). This backfired as bob iger's wanted to keep kevin.
Bob then resorted to a malicious move by pulling joke tweets as a reason to blacklist james gunn. Keep in mind they have no problems with allowing unpleasant drunks like Robert downey jr and johnny Depp to headline films from disney. They were kept on mainly because disney still likes them.
But james gunn is no fucking pedophile. Warner bros can be an amazing studio for gunn to work with with the dc cosmic side. Similar to how joss whedon was able to deliver his best work on justice league.
