This was too absurd and hostile for me to continue listening.
I asked myself whether I thought the author was bad at writing, and realized I fell into their trap.
I asked myself how lost and angry someone has to be to write crap like this, and realized I did it again.
Some people have a real knack for being so defensive and insecure that they invite their own pain. They unwittingly coerce people who meant them no harm into doing so. Everyone is a victim for trying to take this blog post seriously.
First, the author is not assuming bad faith. They are saying that judging people is common pitfall. And the "hating or dismissing people for misunderstanding the thing you documented badly" is something I have seen done so many times, that yep, it exists.
But second unrelated thing is, sometimes there is a bad faith. Refusing to accept that bad faith situation can happen just makes it massively harder to solve the issue. It empowers the person acting in bad faith.
