The writer is an academic, a PhD student, so they likely have little industry experience. Presumably extremely smart and capable in their domain, but not well informed about the industry beyond what they have read in history books about old-timey programmers.
Also pretty clearly not a native english speaker/writer (I'm hoping based on how substandard their english skills are). It may not be entirely fair, but the poor writing pre-disposes me to not give much merit to their arguments.
