//I don't know why DC behaves so awfully to its audience and its characters. Arbitrarily killing, retconning, and breaking apart beloved families and teams for no other reason than shock value. You can't keep an industry afloat on shock value. You have a dedicated audience, so why drive them away so adamantly?
If we’re to believe Tom Brevoort, we know that Marvel deliberately irks fans because apparently controversy helps sales. I don’t know if DC believes similarly, but wouldn’t be surprised. On the good side, however, I think DC’s been better about that in recent months, and we can see it in what they’re doing with the Flash Family: they brought back original Wally but kept New 52 Wally without killing or marginalizing either of them (in fact, younger Wally’s doing better than he ever has). That’s a huge improvement. It seems like they might be bringing back Jay, although that remains to be seen yet. And of course Barry’s still going strong and hasn’t been written out either. So that makes me hopeful.
But they still do it sometimes, because I’m guessing you’re thinking of what was done with New 52 Superman. And that was definitely pretty terrible and shows that they’re still making fandom-splitting mistakes. I’ve not read any New 52 Superman and don’t have any emotional attachment to him, but I feel sympathy for fans who rightly feel upset or betrayed.
