How many have to exist before it can be considered "progressivism"/"diversity" then? Also can you provide those examples that occurred post-Disney? As a huge marvel fan it should be easy for you do. As someone who isn't a huge marvel fan I can think of several off the top of my head that occurred pre-Disney.
Miles Morales (Spider-Man), original character: Peter Parker/Spider-Man, first appearance: 2011
Jane Foster (Thor), original character: Thor Odinson, first appearance: 2014
Riri Williams (Ironheart), original character: Tony Stark/Iron Man, first appearance: 2016
Laura Kinney (X-23), original character: Logan/Wolverine, first appearance: 2004
Sam Wilson (Captain America), original character: Steve Rogers/Captain America, first appearance: 2014
Carol Danvers (Captain Marvel), original character: Mar-Vell/Captain Marvel, first appearance: 2012

Disney purchased Marvel in 2009(let's be honest 2010 is closer to the real year), only 7 of the 10 you listed occurred under Disney's watch. Big marvel fan indeed. Since you listed 7 times a race and/or a gender was swapped (I won't bother differentiating between swaps vs additions, e.g calling Ghost Spider a swap is a massive stretch.) under Disney as proof of "pushing progressive ideologies" I must assumed that is your threshold for something to be considered a trend. Here are 4 (plus the 3 your listed) times a race and/or a gender swap occurred under the previous Marvel owner's watch.
Michael Clarke Duncan as King Pin
Nick Fury (Ultimate Marvel Team-Up)
Lady Bullseye
Miss Sinister
Its almost as if Marvel did this sort of thing before Disney was involved, interesting.
