It basically already has since they started developing dbt Fusion, so in that respect this probably doesn’t change much.

I expect they’ll keep developing Fusion but possibly as even more of a commercial-only offering than it already was.

What's the problem specifically? Are you banking on some future features? Can't fix the bugs yourself? Worried it won't be compatible with future data warehouses?

I know people don't like it these days, but you can just continue to run old software.
