It's been interesting as a comic book fan to watch this play out. No one used to give a shit about Iron Man and Thor. Marvel sold more books than DC and most of those were X-men titles. After the success of the X-men movies the X-men books got a big creative push. Fast forward to the MCU success and they kinda became also rans. CEO Ike Perlmutter apparently likes the Inhumans a lot and they were effectively set to replace mutants in the comics and movies but no one else likes the Inhumans as much as Ike Perlmutter and the plan fizzled out. Ike Perlmutter is also a racist piece of shit by all accounts and I don't remember why he still has a job. I don't read comics anymore but I pay attention to them and I think they're starting to undo ten years of neglecting the X-men but it's going to take a while and they seem content having the Avengers be their banner team.
Kinda weird they never neglected Spider-Man but he's so core to their brand it's less surprising than letting the X-men rot. When I was a kid getting into comics Spider-Man was in a dark time with an ongoing storyline that lasted years that everyone hated. His books have been well received for about 20 years even without film rights. For whatever reason he got priority over what was historically their highest selling titles even after a shift to lower tier characters
Superhero comics are weird. No one should read them
