This article is so poorly researched and written, that it's not really worth taking seriously. I hope no-one does. The writer clearly doesn't understand DevOps or PERL, and just grabbed some superficial ideas from here and there to fill a low quality journalistic word count.

People who are familiar with, and use Perl on a regular basis, are already aware. (TLDR: never capitalize the full PERL; the language is Perl, the executable is perl, and anyone with much experience understands and communicates this difference.)

It is worth noting this SO answer[0], which is a reasonable heuristic when people are talking about Perl. (And, IMO, one of the few times to ignore pedantry is when it's being used as a Shibboleth[1]).
