Most of nvidia's revenue comes from data center scale out. They will loose their ass if local models win.
And I don't see a future where datacenters lose much to open models. I've ran local server rooms before clouds were a thing. Cooling and power is a very expensive pain in the ass. You're not dropping a rack of local models in most buildings without breaking the local power grid.
Open models are great for everyone except anthropic and OpenAI.
