By 'it' do you mean the ending? Most people don't dispute it's probably as explicit as they could go without getting heat from up top and it's clearly capable of getting it across even for younger kids. Speaking for myself though, I just don't see that same message/concept as being expressed in the same readable way throughout the series. Which lessens the potential benefits and impacts of what they've done because it's limited to the end of a show that was dropped from television and relegated to the internet.
I worry about how much new ground is actually being broken here. It would be easy for a network to argue "Oh that was just on the internet, not television, standards are different" or to continue to hold the line on prohibiting explicit depictions/identities, especially on an episode to episode basis in comparison to a finale. Now maybe that kind of super incremental change is all we can hope for right now, but I still think, perhaps naively, that a cultural fight over this issue is winnable given the way the rest of television is going. But that requires a catalyst to set it off, and I don't see anyone willing to hold the line and go public / get fired over something like this.
