The hacker ethos is a pretty old concept that hasn't been written all that much about much since the early 2000s except by Paul Graham, and that's precisely the sort of "suit" association that the old hacker ethos antagonized, so the concept lost luster.

Regardless, the old hacker ethos was very much about individuals creating and disseminating knowledge to empower other individuals, copyright was derided when it got in the way of that.

What does OpenAI do? It uses knowledge to disempower the individuals holding it and sharing it, and giving it to themselves to sell to companies and create power dynamics that are extremely un-hacker-like. Now knowledge has less power to set you free from the monetary or coercive power of the suits and the Government.
