I'm pretty sure you can safely ignore a lot or most of this article. This is not my area of expertise, but from what little I understand, it miscontextualizes a lot of true facts and abuses a few words (semantics is everything) to give the wrong impression about what central banks are, how they work, what the incentives are, what metrics mean and which ones matter.

I could be wrong, but I'd wager if we had a handful of economists in the comments section they'd generally agree, but would have a much better explanation than me.
