There's also significant alpha in releasing open weights models. You get to slow down the market leaders to make sure they don't have runaway success. It reduces moats, slows funding, creates a wealth of competition, reduces margin. It's a really smart move if you want to make sure there's a future where you can compete with Google, OpenAI, etc. There's even a chance it makes those companies bleed a little. The value chain moves to differently shaped companies (tools, infra) leaving space for consumer and product to not necessarily be won by the "labs" companies.
