I think this starts with the title, "Signs of an Immature Software Developer". This immediately puts the reader on the defensive, because nobody wants to be called or considered immature. If a junior developer were to read this and see some of their own mistakes, I think they would be unlikely to be in the right frame of mind to take the feedback onboard and try to address it. The article doesn't appear to be following its own advice, to hone your communication skills. I would suggest having a(nother) read of How to Win Friends and Influence People. A better title might be "5 Growth Areas for Junior Developers", with a corresponding flipping in phrasing of the subheadings (e.g. "Being a Tech Zealot" -> "Being Pragmatic", "Lack of Team Focus" -> "Team Focus").
