That is not in dispute. You are misunderstanding what we are talking about, which is branding. That means what brand, what label and image, is presented to the public. Disney releases adult material under a different brand, to fool people who don't pay attention into thinking it's not a Disney picture when it actually is.
Did you read the article I linked to? The Touchstone pictures were not co-productions because Touchstone did not exist as a separate company, merely as a production unit within Disney. They were 100% Disney productions, but they were labeled as "Touchstone."
I think we have some cross connections here.
I never said Touchstone wasn't made by Disney. I said they aren't credited as Disney. Which is the same thing you are saying.
The Marvel movies
are credited as Disney films. The logo doesn't show up in the opening credits, but Disney is credited as a co production company, and Disney is all over the closing credits.
They
are branded Disney, because the Disney brand is all over the credits. The Netflix app blocks screenshots so I can't take one and show you, but if you pull up an MCU film and go to the credits, Disney is all over them. I just checked with Dr. Strange. IMDB also lists Disney as co-producers if you don't want to pull up a movie and scan through the credits (which I don't blame you at all

) but we know IMDB isn't always the best source, which is why I tried to do the screenshot. Here's the Endgame link anyway:

The Touchstone films are not branded Disney, because the Disney brand in not in the credits. I totally agree. That's the entire point of Touchstone. So the Disney name did not appear in the credits of those films.
Disney is not distancing its brand from Marvel at all. Disney is all about combining the two brands. I mean, just look at Disney Day two weeks ago

. Disney is integrating them so if you think of one, you think of the other. If you ask a random person, they know Marvel movies are made by Disney.
Could Disney make an R rated film and just take their name off of it? Sure, I guess, but I don't know if I buy that happening with how much Disney has done integrating the brand's.
Edit:. Could we just not be agreeing on what constitutes branding? The Disney name is credited on the films and all over the closing credits, to me that counts as branding, as they attached their name to the product, even if the logo at the start of the film is Marvel. Disney doesn't credit itself as Disney on R films.
