As someone who have always used curl and wondered why I often see wget quoted in READMEs (as how to obtain some remote file), I quite enjoyed reading the write-up.
My take-away was that a) I am not missing out by staying with curl and b) the use of wget is likely due to being part of GNU.
You did notice this was written by curl's author? I only noticed after I read it and without that knowledge thought it was rather a pathetically biased article.
But you can't expect developers to be impartial about their own code and it was my fault for not noticing the disclaimer the first time. It reads completely different with that framing in mind, but still if I was looking for the definitive reason that one tool was recommended over another I'd consider the point of view of the developers as a starting point rather than an open and shut case.
