This perspective is only relevant if we assume nobody on HN ever posts maliciously. Some of the circles here are small, incestuous, and probably have some resentment. Other times, there's clear botting - very hard to talk against Elon or his companies without a load of down votes.
Needless to say, the OP could be right but they could be right without proof. Or proof would out them. Or it's malicious posting. Don't take anything on the internet too seriously, even in such sanctimonious spaces as HN.
I always thought it was people who were married to their book, or just fanboys. Some of these accounts that jump in to defend are quite old.
