Fully agreed that there's much to criticize about Brave, but the parent comment is talking about isn't just criticism _per se_, it's a higher proportion of poorly-reasoned and surprisingly negative comments than one would expect. I've noticed it too, and it reminds me of nothing more than Android-Apple threads in the early 2010s.
I doubt this is a complete explanation, but a lot of the nonsensical comments I've seen come from Firefox fans who can't deal with a browser neutralizing one of the most compelling arguments against Chrome (privacy), so they have to pretend that Brave's odd business model (which is totally worthy of criticism!) has flaws that it doesn't, particularly as experienced by the user.
I haven't come across the Brave fanboy side much on HN, but totally believe that they're out there. I'm personally a Brave user but not a passionate one; if I was forced to switch to Chrome with ABP et al, I doubt I'd much care.
