Despite the obvious implications of their sales slump, I strongly encourage Marvel Comics to pursue “diversity” by producing products their customers clearly do not want, even if it takes Marvel into bankruptcy.
The Social Justice war is FAR more important than the mere profitability of a public corporation whose stock is held in pension funds of those surviving elderly workers who are about to attempt retirement after nearly working themselves to death.
Marvel makes their money off of movies now. The comics are a side line. They want to have a "diverse" cast in the movies but can't be sure how far they can push it. But they can experiment in the comics if not on the big screen. So they will continue to try to make their existing and established heroes into gays, minorities, and fascists in the hopes that one (just one!) sticks so they can port him/her/it over to the movies as the "new" Iron Man or Thor or whatever.
