I understand the pain. Though I am someone whose been more of a recluse in this fandom I still feel a since of community here. As for seeing the Mane6 and the fate of this fandom, I am neither an optimist or a pessimist. The only advice I can give is not to simply give up, as cliché as that sounds. For you never know what is around the corner.
similar to how Adventure Time set up Shermy and Beth as backdoor pilot for sequel series the MLP FIM final episode sets up Boruto type sequel series with how things look in future
I doubt it. Their external appearance, maybe, but they never did anything marketable with the changedlings, while they still used the old ones in toys. But their redemption in itself, probably not - that was pretty much the only way they could go if they touched them again. Like Discord and Starlight, they were too powerful to stay alive and evil at the same time.
