I think complexity used to sell (real architects used abstract factory factories). Today, simplicity sells and while far better I think it can lead people to do dumb things sometimes. There isn't any problem with simplicity of course but rather what people define simplicity to mean. Sometimes it means things like "let's write our own database", because it is "simpler".

Right now, "simple" is meant to translate as "good" for the reader and whatever writer wants it to mean. I'm glad, at least, that the article provides an example (React vs plain Javascript). I don't know for sure but I suspect there are at least some valid arguments for using React vs just grabbing dom elements in Javascript.
