As I read it, the criticism of TFA is directed at how people actually use the notation, not how it ought to be used in an ideal universe.

But people misuse words and notation all the time without anyone arguing they're ridiculous. I use dBs on a daily basis with plenty of other people and never have any trouble. Indeed, we'd struggle if we had to use something else.

That only indicates that you haven't found the many angry blog posts yet, not that they don't exist :)
