How stopping using hyperscalers models on their infra would "get as much of this capability into the open as possible"?

Either "we" create models better than commercial state of the art (by using whatever means).

Or we use open models AND fund organisations building such models (could be by purchasing service from these orgs or donations - in which case would these orgs be different than hyperscalers?).

But i dont see how just hosting the models on some private servers would give us an edge?
