I don't think it's cool to take a common and ambiguous term like "power" and claim that it will now only refer to a single, narrow meaning. It's not constructive. Better to qualify the term in a way that everyone in the discussion knows what you are talking about.
The original author clearly has a point to make and providing an explicit definition of the relevant terms helps communicate them. If you want to discuss something else about "power", the comment section of this article is probably the wrong place to do so.
