Fuck you money was always a lottery ticket based on OpenAI's governance structure and "promises of potential future profit." That lottery ticket no longer exists, and no one else is going to provide it after seeing how the board treated their relationship with Microsoft and that $10B investment. This is a fine lifeboat for anyone who wants to continue on the path they were on with adults at the helm.
What might have been tens or hundreds of millions in common stakeholder equity gains will likely be single digit millions, but at least much more likely to materialize (as Microsoft RSUs).
