How does that address the issue? I would have expected them to do that anyhow. Thats what a lot of businesses do: let another company take the hit developing the market, R and D, and supply chain, then come in with industry standardization and cooperative agreements only after the money was proven to be good in this space. See electric cars. Also they could drop that at any time. Remember when openAI stood for opensource?
Neither mention anything about open-source, although a later update mentions publishing work (“whether as papers, blog posts, or code”), which isn't exactly a ringing endorsement of “everything will be open-source” as a fundamental principle of the organization.
