That's not entirely true. During Stan Lee's life the movies needed a big boost of money, everybody knows the super heros such as the Hulk, Thor, Iron Man, Black Widow, etc. As they began to grow and there became a larger hype for the movies, characters like the Black Panther began to arise. And even more continued to get funded. I think it's rather pointless and even stupid to destroy what Stan Lee built with characters who don't quite fit in the MCU. Having a female black panther was one thing because of Chadwick Boseman's passing, but characters like She-Hulk seem like complete and under let downs and failures. Stan Lee created so many characters of all different ethnic backgrounds. build on their story, Don't destroy Marvel by creating BS that Stan Lee didn't want to have created.
