I don't mean to specifically call him out, but I worry that the complexity is what keeps him popular. And then you have someone like Pieter Levels just slinging raw php into production and not talking about anything like Suspense or Server Side Rendering or Hydration.
They both get to the same ends (well Pieter Levels makes magnitudes of order more money I think) but there is a gulf in complexity. I'd actually argue something like Nomad List is much more feature rich than anything I see from Theo.
