First off, it's too soon to tell why that guy flipped out and decided to commit vehicular manslaughter, however I understand the frustration felt by ferryman since, well pattern recognition is a thing after all.
Are you for real? a) there was nothing harmless about it, b) what you call "censorship" is, in fact, simply criticism (the shout is still there, no?). And the "essay" is just Brandolini's law in application.
Kinda shocking that a harmless and backed up assumption was just made here, and was responded to with accusing essays. I'm all for the community guidelines but this censorship is worrying.
Not to mention a strategy right out of the alt-right playbook. Make vague claims to occupy people with refuting them while ignoring facts and only triggering emotions. Maybe you're confusing Metal Storm with Telegram?
