A few things that stood out from Scott Benson's post:
It supports the narrative that Alec was mentally ill, that he was bad, but had gotten better ... except the twist at the end is that allegedly he hadn't gotten better, Alec had just started abusing other people, not Scott. And he had no idea until just these past few days.
Alec wasn't a broken stair, because apparently nobody ever talked about what he was like to other people. Ever. A broken stair requires you to be a well-known secret within the community; apparently everyone knew but nobody ever shared this information until last week.
The one time he was called out on his behaviour in the account, through Bethany's now-deleted passive-aggressive Twitter alt, he took what was said onboard and started working hard on his problems. To Scott, he was much, much better from then on. So maybe if people hadn't been so terrified of conflict or confrontation they could have resolved the problem, rather than letting it go for years and all the suffering that allegedly came with it.
Scott says at one point that he was still working 7-hour workdays from 2015, as if this is a massive undertaking rather than one hour less than most people do a day.
There's a little bit where he says that apparently women dating Alec were being asked to give something they weren't willing to, and it comes across as less 'Alec was an abusive boyfriend' and more 'Alec had girlfriends who expected to get into the gaming industry through him'.
There's also a bit where he makes note that Alec said that every woman he'd dated had been terrible, as a sort of 'if you run into assholes every day...' aside. Fun to remember that also appears to apply to Zoe Quinn as well.
It's all from Scott's perspective, which is fine and fair - wouldn't expect him to talk for anybody else. Except it does mean that, once again, we are left with not a single other name attached to a solid accusation. He says all these things that apparently he's just now been made aware of that Alec has been doing, before, during and after he was working with him. From his description, it sounds Alec came pretty close to a proper psychotic break during the making of NiTW - and I have no reason to disbelieve that.
It's the stuff after that I find thunkful. I said before I'm not sure how much we will be able to trust any accusations that come out after Alec's death, because he won't ever be able to refute even the most outlandish claims. So it sure would be nice, and will most likely never happen, if people who were to claim he was abusive were to be able to back it up with anything in the way of evidence. From the sounds of it, there should be copious amounts of it. Hell, Scott should have a whole lot, considering if his account is true that he and Alec would have long chatlogs over various media to show.
If you're going to the effort of making sure everyone knows the guy who just killed himself was a terrible person, you'd think you could at least provide receipts. We'll be waiting a while, though, I'm guessing.
