I don't understand a lot of the anti-LLM venom within this specific context. Debian doesn't have to worry about stealing GPL code, so the copyright argument is nearly nil. There's still the matter of attribution-ware, but Debian includes tons of attribution and I'm sure would happily include anyone who thinks their OSS might have been trained on.
So leaving that aside, it just seems to be the revulsion that programmers feel towards a lot of LLM slop and the aggravation of getting a lot of slop submissions? Something that seems to be universal in the FOSS social environment, but also seems to be indicative of a boundary issue for me:
The fact that machines have started to write reasonable code doesn't mean that you don't have any responsibility to read or review it before you hand it to someone. You could always write shit code and submit it without debugging it or refactoring it sanely, etc. Projects have always had to deal with this, and I suspect they've dealt with this through limiting the people they talk to to their friends, putting arbitrary barriers in front of people who want to contribute, and just being bitchy. While they were doing this, non-corporate FOSS was stagnating and dying because 1) no one would put up with that without being paid, and/or 2) money could buy your way past barriers and bitchiness.
Projects need to groom contributors, not simply pre-filter contributions by identity in order to cut down on their workload. There has to be an onboarding process, and that onboarding process has to include banning and condemning people that give you unreviewed slop, and spreading their names and accounts to other projects that could be targeted. Zero tolerance for people who send you something to read that they didn't bother to read. If somebody is getting AI to work for them, then trust grows in that person, and their contributions should be valued.
I think the AI part is a distraction. AI is better for Debian that almost anyone else, because Debian is copyleft and avoids the problems that copyleft poses for other software. The problem is that people working within Free Software need some sort of structured social/code interaction where there are reputations to be gained and lost that aren't isolated to single interactions over pull requests, or trying to figure out how and where to submit patches. Where all of the information is in one place about how to contribute, and also about who is contributing.
Priority needs to be placed on making all of this stuff clear. Debian is a massive enough project, basically all-encompassing, where it could actually set up something like this for itself and the rest of FOSS could attach itself later. Why doesn't Debian have a "github" that mirrors all of the software it distributes? Aren't they the perfect place? One of the only good, functional examples of online government?
edit: There's no reason that Debian shouldn't be giving attribution to every online FOSS project that could possibly be run on Linux (it will be run on Debian, and hopefully distributed through apt-get.) Maybe a Debian contributor slash FOSS-in-general social network is the way to do that? Isn't debian.org almost that already?
Before LLM did code, you could at least have assumed that the submitter had written it (at worst, copy-pasted large parts of it), even if they had not read or reviewed it. Furthermore, writing (even copy pasting) is quite labour intensive, so there was that hurdle too.
