Do you think it's possible that Paapa will drop out of casting?

Does anyone else see the possibility that Paapa will drop out of casting due to the large amount of backlash? Its not 100% that he has been cast, only that he is in final negotiations. But i think its possible as He has already made his Instagram account private.

I could see him being transferred to a different role because he is an amazing actor.

Clarification: i think he will be a great Snape, and I support any and all casting choices
