I'm the opposite, I think they should be able to hold on to the tooling to use it to further develop their processes and have the most up to date version, while releasing past versions. This is similar to what some game companies did that was pretty open. For example Quake was released as open source by Id Software in 1999 after the game's initial release 1996. (And Quake 3 was open sourced in 2005 after the game was originally released in 1999.) I think that is what would maximize the public's benefit.
Your suggestion only opens it up to companies with very large dollar budgets - do you think any of them would release their resulting model? So how does the public access any of it? None of the ChatGPT models are ever actually released then and unlike the open sourced Quake example, the public doesn't benefit from access to them. It would be like if Id software just released its tooling for other game companies to copy, but not the actual game.
