If I correctly catch the drift of your argument, you're saying “engineering is objective”, so there is such a thing as a right and wrong choice in any given situation. ...well, to the extent that that's true, the word “taste” is a poor choice of words then. Actually, I think that's the case for this article. I think the article is fine, but the title and “taste” as a choice of word is not great. The article is more about intellectual humility and subordinating your individual priorities underneath the requirements of the project, which is all perfectly fine.

There are some domains where the word “taste” can still properly be applied, for example “vi vs emacs” comes down to individual taste. But then, “emacs people have poor taste” is something that only a narcissist would say. (The “narcissism of small differences” is a well-studied phenomenon).

Or perhaps one uses this choice of words because one feels some sympathy for people who say this in other domains, like “This room, filled with IKEA furniture and film memorabilia, was decorated in poor taste”

… either way, the red flag seems to stick.

The reason it's worth mentioning is that the notion seems to be catching on, and I've seen it applied, for example, in hiring decisions, where I think it's quite dangerous and counterproductive. It lends itself to rationalizing hiring only like-minded people, even where there is no objective ground for preferring one candidate to another.
