You made it look like it was such big deal despite the fact that the marvel doesn't actually have anything to do with it. They also didn't do it because they have "faith" in them (the fact that they chose Miles who carrry the Spider-Man name make it clear that they don't), they did it to get diversity points.
You also make it looks like Marvel have gazillion legacy shows for Disney+. I mean, they have what? Two shows? Ms Marvel (who is the biggest and one of the only two successful legacy characters Marvel has) and Hawkeye. They actually playing it incredibly safe and not taking risk at all.
