The point the author is trying to make is perhaps a reasonable one, but what an inappropriate communication style. I don't know if the author realizes the tone is so off-putting, but I've found that supportive feedback and constructive criticism goes a lot further in professional environments than name calling and insults. Put another way, if someone on my team at work communicated like that I'd have a conversation with them about more effective approaches less likely to alienate or offend colleagues.
There appears to be an uptick of hyper-agressive technical posts over the past several years. I'm not sure where it started, but I'm hoping it burns itself out soon.
(If you're the author, I apologize for calling you out on this. Nothing personal at all, I just wanted to make the general point about tone.)
