Open weights are framed as a way to diffuse AI value across more firms

The argument is that open weights matter because they let many firms build their own closed-weight systems, diffusing AI’s benefits.

The position being critiqued is not really anti-open source in the abstract; it is against a future where only one or two companies control closed weights, extract rents, and hold leverage over the rest of the market.
