Reno's last post about this is very clear. Alfa clearly crossed major boundaries and made someone he claims to have cared about feel totally awful. I don't see anything here that would make relitigating the entire case again anything but pointless and painful.
I don't know if Alfa's real life career should be impacted (I can see people not wanting to work with him for sure), and I'm sure that his parents shouldn't face threats.
I don't think it's a good look for him to try come out better from this by smearing Reno. If he wants forgiveness for his actions he needs to truly acknowledge the scope of what he did and try to seriously make amends for it, not keep attacking the person he hurt.
For people who have doubts, I would point to how much detail is in Reno's depiction of the assault vs Alfa's. He has to leave out a ton of emotional details that obviously factored heavily into what happened.
