My feelings exactlyThe problem is that they had a hero (Wanda) do something terrible. That in and of itself isn't that remarkable as has been pointed out lots of others have done terrible things as well and recovered narratively. This is different from previous examples for a couple of reasons. First, it was the method used to abuse the hell out of the X-Men as a line. The consequences of HoM and the editorial mandate that caused it have continually bludgeoned the X-Books and mired it in a state of continual misery porn ever since. Second, Marvel flubbed her half assed redemption stories. CC is vague and wasn't followed up on at all, Uncanny Avengers is generally viewed unfavorably from the X-Fandom's perspective (For a lot of reasons' I'm not going to get into here) in fact her actions are generally viewed as a continuing negative rather than any kind of redemption.
This brings us to the present where a sizable portion of the fanbase (the X-Fans) dislike her. However, personally I'm encouraged by whats happened so far. Hickman is not the sort to leave dangeling plot threads and like it or not, it makes sense that she wouldn't be that popular with mutants in the MU. However, whatever else she is doing, even when failing as hilariously as she did in X-Men Empyre, she was sympathetic to X-fans, and that's something good. Hickman has stated that one of his overarching goals for the X-Line is to fix its status quo, to get it out of the misery-porn its been mired in since HoM. It only makes sense, to me at least, that part of that would be to actually have a solid redemption for Wanda. It won't be quick because good stories aren't (and Hickman is never quick), it will probably be rough for her because redemptions stories almost always are but I still think that its one of the goals.
