The Barb abuse thing is all speculation, isn't it? I'd never have said they were good parents tbh but I never thought there was evidence of what Kiwi Farms etc accused Barb of. Having said that, I never followed it in any detail.
Agreed though, the entire Chris Chan story is horrendous. There's a really long documentary thing on YouTube about it - like 50 hours and counting, last I looked - but so much went on, it needs to be that length to cover it all. Think it's (hopefully) something that couldn't happen today, where it's harder for trolls to fade into the background.
I never saw it ending well but I also never expected this would be the final saga.
