Not sure if anyone else has said this yet because I haven't read everything for the past few pages, but I saw some people confused how doing this could result in him getting a pay raise.
I don't think it's hard to imagine at all.
If this had succeeded and he'd done the interview circuit and came out of it with name recognition many orders of magnitude beyond what it was before, and he had massive numbers of sympathizers, and he had a huge boost in Twitter followers, mentions, he's all over the news, etc. - I think it's not unreasonable for him to have felt that would have put him in a better bargaining position for a raise on Empire.
Or have just naturally resulted in that.
Or he might've thought maybe people would raise money for him or some rich black star might give him some money or who knows what. The fact is, he sensed it would bring money, fame, and opportunity and it was/would have. He wasn't wrong.
