> But we are talking about a social contract, which is not quite the same thing. The social contract is what leads some devs who previously enjoyed publishing their work openly to no longer feel the same way.

Perhaps this illustrates a fissure that was always lurking under the surface, then. The social contract that I've personally always attributed to FOSS communities was that attempting to restrict how people downstream of you use code is illegitimate, and that licenses like the GPL were meant to use copyright law to achieve something that resembles the state of affairs that might exist if copyright didn't exist in the first place. That's what the whole concept of "copyleft" always seemed to imply.

Now we have a new class of technologies that is admittedly fraught with a wide range of risks and pitfalls, but also a lot of promise to enable people to actually put the "four freedoms" into practice in ways they couldn't before, and we're seeing people who have normative opinions about AI derived from other, unrelated principles trying to circle the wagons and exclude those use cases. That is what seems like a breach of the social contract as I've always understood it.

> Did they mean literally CTRL+C, CTRL+V or something broader?

Given that FOSS licenses were always constructed to function within applicable copyright law, I don't see how they could mean anything else. "Literal CTRL+C, CTRL+V" is the only thing copyright has ever applied to, and the whole point of "copyleft" was to lessen the restrictions on even that.
