Power of the command line

The article includes this as its first lines: "Disclaimer: I am not advocating any specific tools or methodologies, I am simply sharing workflow I find to be efficient and pleasant."

Why bother disclaiming this? Why should the author Rosipov care if he advocates specific tools or methodologies (he does, in the very next paragraph)?

Is there some active force out there that discourages people from advocating or talking positively about command lines and related tools? Is these some force out there that encourages talking negatively about command lines and related tools? Because if there is, that particular force is so in the wrong, for any number of reasons.
