If there was ever a time in 40+ years of #FOSS history to tell our #copyleft-hating FOSS friends that they erred in their license choices, now is the time.
If they don't switch, they're giving hand-outs to the proprietary software companies. Now, in an entirely new & #disturbing way.
I really think these cases where proprietary software ends up in #LLM training sets & actually creates risk are exceedingly rare, if not entirely hypothetical.

Re: “polluting”, my reply is: https://fedi.copyleft.org/@bkuhn/116426437134023846 (elsewhere in thread).
Re: “copyleft-only #LLM”: I didn't propose that. I proposed copylefting the human-modified output of LLMs.
Re: “two scenarios”: IMO you propose a false dichotomy.
I hope you come to one of #SFC's public sessions on this, as I'd be glad to talk more about it, & this discussion doesn't lend itself to online debate because it's so complex.
> Re: “copyleft-only #LLM”: I didn't propose that. I proposed copylefting the human-modified output of LLMs.
You didn't propose it, but @ossguy brought it up here: https://fedi.copyleft.org/@ossguy/116411885602822736
You two have been speaking fairly collaboratively in this thread, so I'm assuming relatively synced at the moment. Since I presume the goal of "only train on copylefted [and implied, compatible] software" would not be, from your end, to erase copyleft, my assumption here is that the hope was that the output was also copylefted.
And I presume reading this that you do hope that would be the presumption: https://fedi.copyleft.org/@bkuhn/116428083639528264

Have you seen attribution lawsuits anywhere in the 50 years of the BSD license?
Of course, you have a point. But we're facing possible compulsory licensing if we don't improve our strategy. We may do the wrong thing, & if a BSD-licensed project wants to burn it down & sue a copylefted project for non-attribution infringement, let's deal with that when it comes.
& I'm speaking as one of the few who has actually been threatened with such a lawsuit.
@bkuhn @dalias @zacchiro @richardfontana I don't have them on hand, but I remember attribution enforcement with CC BY to be pretty common, particularly making newspapers update their use of "stock photo" style headers with CC BY licensed photos. I don't remember, off hand, escalation in enforcement to a court case (I feel like there may have been, but usually when attribution requirements are pointed out, people simply comply pretty quickly, since it's not hard to comply with and rarely against interests... LLMs are a change there, since there's not really a way to do so)

I assure you there are few people more familiar with those cases than @bkuhn, even if the two of us are disagreeing right now

However, it's not actually the laundering angle I am concerned with here entirely, it's whether we're turning FOSS codebases into potential legal toxic waste dumps that we will have a hell of a time cleaning up later.
The previous Conservancy post, which @bkuhn linked upthread, indicates that Conservancy does indeed consider the matter unsettled.
Current LLMs wouldn't "default to copyleft", since they also include all-rights-reserved mixed in there. If the result of output of these systems is a slurry of inputs which carry their licensing somehow, their default licensing output situation is one of a hazard.
I note that @bkuhn and @ossguy seem to be hinting at hoping a "copyleft based LLM" with all-copyleft output it a winning scenario. I'm going to state plainly: I believe that's an impossible outcome.
@cwebber @bkuhn @ossguy @richardfontana On top of "potential legal toxic waste dumps" we'd be making them known technical toxic waste dumps.

Any complex public policy litigation takes ≥ 10 years to make its way through the Courts. *Thaler* was an anomaly precisely because Thaler narrowed the issue on purpose to a pointless degree (just to make a point, apparently).
The reason copyleft exists is because rather than wait for the Courts & legislature to make good law, we used the existing system against itself.I propose we design a series of moves that can do the same for LLM-backed genAI.
@bkuhn @dalias @cwebber @zacchiro @richardfontana
What might those moves look like?

it is a bit fun to read that and note I was involved in some way with more than I wasn't. Listing old patent cases is really tangential though.

It's solved with a new copyleft-next clause I have not pitched you yet.
Remember how I keep telling we need to talk every week?

@bkuhn @dalias @cwebber @zacchiro @richardfontana

I'm working on it. It will require good, disciplined behavior by key FOSS contributors and a better copyleft license.
