I think the point is that companies that use Python tend to be able to switch out to other languages where they need speed very easily, where it makes sense; for example, a lot of Python developers got very excited about Go, and now there's mostly-Python apps with certain functionality written in Go dotted about the place. The idea of calling out to services to do things is decidedly normal in Python. PHP companies tend to have more of an issue with this, for various reasons. PHP apps can suffer from the "big ball of muck" issue quite easily, where there's not nearly enough abstraction to allow for parts of the code to be written in other languages. Such an architecture would also require additional deployment steps, vs PHP's "copy everything to the right place", and there's a lot of PHP devs who, while rather good at PHP, are quite resistant to new languages.
