I can't speak for Tyler (the author) but as someone who's worked with him and managed him for over 2 years, I'd say take Tyler at his word versus assigning malice to his writing.
He's a powerhouse of a developer, loves, LOVES the ecosystem and has always wanted to give back as much as he could. He's submitted patches to the core, he did so much for our Elixir CI and felt bad not giving it back via open-sourcing it and then blogging on our platform.
Tyler was instrumental in many of our technical decisions at our company, and I can confidently say nothing he made us buy was unnecessary, and he often worked very hard to save us the smallest bit of money.

Just my 2 cents!
