It sure seems like the people upset about this feel like everyone should be upset too. I don't really care too much. I'm a minority but I don't personally care if fictional characters look like me. For example the black Miles Morales spiderman isn't interesting to me at all despite being a huge spiderman fan since I was little and being mixed.
With most things, I want the original version I'm used to. But I also don't care that there's a black Spider-Man, a Hispanic one, several female versions, etc. Does nothing for me either way.
Maybe it gets a young black or Hispanic child to pick up a Spider-Man comic because now there's a Spider-Man that looks like him. That's pretty clearly what the advertisers are hoping for.
Sometimes it works out. The X-Men team introduced in the 70s that included storm, colossus, wolverine, etc. is now seen as one of the most iconic versions.
OTOH the clone of Spider-Man that was introduced in the 90s was so reviled they had to eventually close the arc and kill him off after about 5 or 6 years of trying to get fans to warm up to him.
