Do you not think part of it is just whether employers permit it or not? My conglomerate employer took a long time to get started and has only just rolled out agent mode in GH Copilot, but even that is in some reduced/restricted mode vs the public one. At the same time we have access to lots of models via an internal portal.

Companies that don't allow their devs to use LLMs will go bankrupt and in the meantime their employees will try to use their private LLM accounts.
