I agree with the points made in this comment. It’s important to remember that people getting dogpiled on can feel pretty awful about it. It reminded me of this Sam Harris podcast interview with a documentary fillmmaker who described her experience of being “cancelled” as being worse than her experience of being kidnapped.
That said, I don’t know how well they address the original comment they’re replying to. The post we’re looking at was posted three months after the impetus for it, so while I do see that the whole experience is very stressful and can make it difficult to be charitable on the spot, the extended period to craft a reply means it’s possible to overcome one’s initial impulses and figure out how to respond. Ultimately, if this post chooses to adopt certain rhetorical tactics (for good or bad), I think Kat and the Nonlinear term do need to take responsibility for these tactics. And to my understanding, they have—for instance, in this comment Kat says that some of the controversial decisions around inclusion of stuff in the post were things that the team discussed and decided on.
In my reading of the post and the appendix, the point Kat seemed to be making was not that professional assistants would be cheaper, but that professional assistants would have a better upfront idea of what they were getting into, and therefore be less likely to retroactively feel that this was a bad decision. This is consistent with the idea that having that upfront idea could also come with demanding higher compensation upfront before entering into the arrangement; what Kat was trying to guard against was regretting it after agreeing to it.
In a section of the appendix Kat says that she currently has a (remote) assistant charging $50/hour and it seems to be working well:
