@Daz:
Come on, Scorsese, Fincher and Campions latest were direct to netflix
Coppola, the maker of the Godfather movies, is literally trying to get his latest film funded himself
Nightmare Alley was getting pulled from theatrical screenings to make room for even more Spider Man showings, despite Spider Man already being far and away a mind boggling success
The films from the former Fox studios, such as The Last Duel, were in a state of limbo regarding whether they'd even get released at all after Disney bought the company. Mid-budgeted productions are getting extremely rare in general in favor of big budget IP driven films.
Nobody expects their films to do Avengers numbers and compressing everything down to these directors being "Bitter" about the MCU just making more money ignores the entire argument about the MCUs larger systemic effects on the movie business, that are making it harder for certain movies to exist at all.
I think all of these problems really suck, for sure. Ideally, there should be room for all types of films, but I know that is not the reality of it. It does feel a bit unfair to blame the MCU for that, even though of course it helped increase the trend of studios not being willing to take many risks and only invest money in known franchises, which started in the early 2000's. But it's a case of "hate the game, not the player" to me. Blame the studios, producers, the system in general instead for only caring about how to make as much money with as little risk as possible. It's like being bitter towards football because it gets more air time on TV then, uhh, polo.
Also, we must surely acknowledge how this whole thing is a clickbait farm at this point, right? Scorsese made one, One, ONE statement and a followup clarification and thats it, and yet it has been regurgitated and repurposed ad nauseum to the point where It seems many people believe he does nothing but seethe with venom at the MCU all day. Heck, the present Sam Jackson article that started all this refers to a snippet from an interview on ANOTHER site, itself a response to scattered quotes from other interviews on other sites.
Or we could dig up all the quotes where these filmmakers praise other effects driven movies, like how Scorsese liked the Raimi Spider Man movies (no wait this place is largely anti raimi Spidey, this would just be another strike against scorsese, natch)
The whole Scorsese outrage was completely overblown. He's one of the best filmmakers of all time and only made a mild comment that the MCU films weren't to his liking, basically. The fan reaction was ridiculous, especially the attempts to make him look like a grumpy, out-of-touch grandpa.
But ultimately, The MCU is the most popular movie/TV thing on the planet. If you're a fan congratulations, your team has won pop culture. Is that not enough? Does it really matter that these directors are not fans? If its a matter of tone, of "how they say it", again why should that matter, its not like they're saying "people who like the MCU are stupid". Just because someone is dissing somethiing ones like doesn't means they're dissing one personally.
Eh, I think it's pretty human to be upset when someone trashes something you love, even if it's not the most mature reaction. Especially if it's someone you respect, it can be a bit disheartening. At it's heart, it's insecurity about your own opinions and taste. If someone insults something you like, he is in a way also insulting your taste, and some people have a problem dealing with that. I don't feel personally insulted by these statements myself, but I know I can get upset and defensive if something I like is insulted. I agree though that ideally, one shouldn't take it personally.
I do think tone does matter, though. I didn't really feel offended when Coppola badmouthed the MCU in very harsh terms, but I did think he was acting like a hypocritical ass there.
Conversely, I'm assuming them liking the MCU would have been pretty cool and permissible?
Yeah, it kinda would, in the same way your grandpa would get coolness points if he plays a round of Mario Kart with you or watches the Simpsons (one can tell I'm a 90ies kid 
). Like, I recently learned that Jamie Lee Curtis is a big One Piece fan when I saw a video of her on a panel at Comic Con, where she was asked who she would like to play if she could pick any fictional character, and she answered "I'd be Nico Robin." And I instantly felt a great deal of sympathy and admiration for her. I think that's normal, right? To be happy to "meet" someone who likes the same things you like? I don't think there is anything inherently bad or wrong with that.
@andre:
I can't be quiet. Godfather 3 is so much better than the worst MCU movies. It has its issues and was extremely disappointing, but it's not actually a bad film and is leagues better than Thor 2.
Eh, maybe I need to give it a rewatch. It's been a few years since I've watched it for the first time and I just remember thinking at the end "I do not want to watch this film ever again", which is much harsher than I felt about Thor 2. But that probably had a lot to do with high expectations. So yeah, you are right, that statement was a bit too much.
