That can be said about most of the MCU though. While I think they would give him a movie later, they probably wouldn't have started the MCU with Irom Man if Spider-Man was available. Avengers would probably still be part of the MCU, but would they be the focus of it if Marvel had X-Men and Fantastic Four? GOTG likely wouldn't have been made either. And then that would influence the comics too... We would be living on a completely different world.
Err... I really doubt it. If they had the rights, they would have made an X-Men movie long before Marvel even thought what to do with the Captain Marvel name. Rogue would be on it, called Rogue, and Marvel wouldn't want to push her as anything else. Would they make Storm become Thor or something like that, if Storm was on a bigger franchise? It makes no sense. And the trademark issues... Marvel has created not one, but four characters to hold that. Monica Rambeau, Genis-Vell, Phyla-Vell and Noh-Varr. All of them obscure characters, but with some connection to Mar-Vellor the kree(except for Monica, but she was replaced quickly by someone who did and I'd say that shows how Marvel feels about it). There's no indication that Marvel would ever give it to Rogue or someone like that, in whatever situation it was.
Re-read my post. This is not the point at all. The point is that Marvel wanted to make a movie about Carol Danvers, not any character with the Captain Marvel name. It's about the situation of the movie.
Then as I said, it's a Carol vs Rogue thing, not who actually fits the name the best. Whether you're asking for people to bash the characters or not has nothing to do with that. It's still about which character you think it's better for some reason. Why did you said I was "accusing you" when I pointed that out?
The idea of forcing a connection that never existed just to give a reason for Rogue to take the mantle sounds just terrible, and I think it says a lot about how this idea doesn't make sense for her character in the first place.
