Contributing back is besides the point. GPL is infectious, so all of their code which they aren’t releasing the source of is also considered GPL. So unless they release all of the source code they are still non compliant and I have to imagine they’re wel aware of this.
I have a hard time seeing what we are currently calling “AI” evolve to address issues like this. It’s not real intelligence, it’s just text prediction. It seems fundamentally flawed for use-cases where you need 100% certainty of the answers being appropriate.
This isn’t the AI people think it is. And the only danger it poses is irresponsible use.
