With #1, these remakes reinvigorated the brands. There's simply no argument against them from a business perspective, any personal feelings about them aside. It's not even Iger's idea, either. Disney's done the same thing with straight to video releases of the same titles back in the 1990s.
2 is one of those that's just silly. Disney's doing the right thing. More corporations should follow their lead. Period.
On #3, the benefits of Fox are myriad already and will only grow more valuable over time. As just one example, The Simpsons quietly anchored the first year of Disney+.
#4 isn't much of a riddle. Starcade failed, so they had no reason to replace it. Arcades are extremely niche, and I say that as someone who was literally JUST looking at the Insta of a nearby arcade/bar we like. Pixar Pier makes basic sense from branding AND theming perspectives.
#5 may bother you, but that's only the outer fringe of Disney to begin with. I've got friends within the comic industry -- one who has made millions from selling his earlier drawings from the 1960s and 1970s -- who complain about Marvel, but it's always a discussion of art vs. commerce. Since this isn't art appreciation, the central point stands. None of this has anything to do with Bob freakin' Iger. He's not someone who has a weekly pull list.
#6 is a money industry for Disney and has been going back half a century. I mean, Walt Disney's final words were Kurt Russell. These stupid tween comedies bring in new viewers. It'd be terrible business to throw out the revenue streams of High School Musical, Descendants, Teen Beach, and now Zombies. If you want to say they suck, that's fine. Everyone responds differently to art/entertainment. Those are bread winners, though. I mean, Disney called an entire weekend conference after Hannah Montana's movie overperformed. That speaks volumes about the importance of that demographic to the company's vision.
As for Epic Mickey, if there's demand, they'll license it out to somebody else. The Power of Two came out in 2012. That was two full console generations ago now. And again, none of that had literally anything to do with Bob Iger. The only way he'd even be aware of it is if his kids/grandkids played it.
