I suppose that really depends on what the fan is doing. Are they just an enthusiastic reader? Then I don't see how they can ever be blamed for anything that goes on at a company because what you would ask of them, say, boycotting books, isn't something that they likely want to do. I'm all about taking a company to task but unless a fan is spewing vitriol, making personal attacks, or something that actually causes harm, calling them out is meaningless.
My approach has always been one of pragmatism. The idea that a company is specifically targeting creators and attempting to hamstring their efforts in some sort of machiavellian game, is just absurd. I firmly believe that there is something going on, sure, but I imagine the truth lies somewhere in a more mundane reality like responding to poor sales of books. It isn't a one to one, but the vast majority of editorial interference has appeared to lie with those titles that are doing poorly or eventually got cancelled. Some of the more high profile, ones, however, seem more connected to "world building" disagreements, such as the rumor that there is going to be another Earth 2 book and Robinson left because he wasn't going to be writing it. Batwoman may fall into this one or it may have been because its dipping sales.
Real Talk: I'm a fan of DC characters. I'm not going to suddenly switch allegiences and start reading Marvel. They just don't interest me. So, as a fan, I have to weigh my enjoyment in books (which I still have) versus response to creators vs. editorial. I am not going to stop getting a book out of protest. So ones options are limited.
