There's a lot and hate of criticism of PHP out there, so some praise and sane opinions are nice to balance it out.
For example, Erlang is painful to adapt to, but in some cases (example: if you build a Messenger app) it will be the best.
It doesn't mean that Erlang is a bad language at all, it is designed for a main purpose in mind.
It's normal to see junior developers and low-quality packages in PHP, JavaScript, Java or Python, it's because these languages are well-documented and rather accessible.
There is no point in making a language needlessly complex.
Which is literally what the article said.
