I could see that. It certainly beats people blaming Kathleen Kennedy or politics, which they seem to be doing for icky reasons.
Neither Fast X (tenth in the Fast and Furious franchise) nor Transformers Rise of Beasts (I don't even know what movie they're up to here) did well at all, and those are the two tentpole IP's for Universal and Paramount, respectively. So the problem isn't exclusively Disney. And as for perceived offensive-ness? For one of the genuine successes of the summer - Sony's Across the Spider-verse - the entire series modus operandi is to be woke ("Anyone can be Spider-man"). So I don't know that, "make stuff your daft uncle finds agreeable" is the answer.
Hopefully, the problem is that people are tired of old people peddling their old trash onto them over and over again. Fast and Furious is twenty years old. Transformers is fifteen years old. You don't even want to know how old Indiana Jones and Star Wars are to young people. Or how old all the films the live-action remakes are remaking are. I think Disney's brand reputation now is just making old stuff over and over again, except uglier and emptier and incoherent, and everyone's tired of it. And because Disney were so successful doing this throughout the 2010's (do we just call this the Twenty-teens?), all the other studios copied them and now people seem all a bit bored?
