It is being pushed very hard that the solution is to keep models under lock and key.

Is not the most major problem with maintaining a healthy society keeping the power of governments and massive corporations in check? How are closed source models supposed to be the solution? I simply don't see it, so to me it reads as propaganda from those powerful entities. Leaving the most powerful software to be only understood, researched, and used by the most dangerous groups is likely the worst thing you can do.
