HN used to lean very libertarian. I might need to say "right-libertarian" to be specific enough. That philosophy tends to tolerate large-scale power structures as long as they're not violating the rights of others and remain subject to competition.

I've noticed a shift away from that in the past couple years. The grandparent post doesn't seem to be left-anarchist though; more like state-socialist. It proposes that some central authority, presumably the US government dissolve or split up large tech companies. The problem I have with that is I fundamentally mistrust large scale power structures and centralized authority. The US government is one of the most extreme manifestations of those things.
