I think there are two take-aways from the statement. One is that it doesn't benefit companies to make strong political statements as corporate positions, particularly things that focus on 1-2% of your workforce. If Disney was saying "kids should stay in school till 12th grade and we make media that supports that idea", that is a pretty generally applicable and benign thing. But saying "we think the core family concept of a father, a mother, and children is outdated and needs to be replaced with alternative models of broken homes, blended families, single parent households as the norm and totally acceptable and should be pushed to kids" is pandering to a very small demographic and ignores that virtually everyone and all the data thinks the classic nuclear family is the optimal path, broken, blended, or single parent homes are not the ideal and shouldn't be pushed as if they were. Doesn't mean that stuff can't be shown, as lots of kids live in those situations, but its the "ideal" part that gets Disney in trouble I think.
Second is just missing the target audience for their IPs because they foolishly think the original target audience will stick around. Marvel and Lucasarts are two great examples. They were bought to bring boys back to Disney, and it works REALLY WELL until they decided to turn those IPs towards girls. It would be like taking Frozen or Beauty and the Beast and making them into mecha war films with a lot of singing and pastel colors, then wondering why boys didn't really show up but neither did the girls.
So Disney needs to just stop preaching from their corporate offices and start making films that are properly aligned with the audiences.
