It is only a controversy when the company advertises it to non-comic readers in an attempt to penetrate new and mostly untapped markets. While the medium does get a degree of freedom, any controversy, such as gay characters, will eventually fade and basically give the company a 15 minutes of frame scenario.
Plus this is the internet, if it isn't blown out of proportion, you are doing it wrong.
Death in comics isn't always bad. I never read any comics with Jean alive until All-New X-men and I don't think it has lessened her death at all. Death in Marvel and DC comics are more about how other people handle them than the actual death. For instance every time Nick Fury "dies" people don't care because of LMD's and he has a habit of faking his death. On the other hand when people like Jean Grey or Nightcrawler die, it has an impact. So even if regular Jean comes back somehow, it won't lessen her death because other characters care about her.
I think that it is good that not a lot of people are leaving for Scott's school. I like him as much as the next guy but I really don't like him lately, he is just too off the charts. At least it is consistent with people not wanting to go, it shows that they have grown to like the school a bit and that they see that Scott is a bit nuts.
