If we're talking about doing everything well, I think that's true. However, if I want to create my own personal "word calculator," I could take, for example, my own work (or Hemingway, or a journalist) and feed an existing OSS model my of samples, and then take a set of sources (books, articles, etc), I might be able to build something that could take an outline and write extended passages for me, turning me into an editor.
A company might feed its own help documents and guidance to create its own help chat bot that would be as good as what OpenAI could do and could take the customer's context into the system without any privacy concerns.
A model doesn't have to be better at everything to be better at something.
