Take a look at #SFC's Principles of Community-Oriented #GPL Enforcement found here:
https://sfconservancy.org/copyleft-compliance/principles.html
While that's tailored to the question of GPL (as opposed to #LGPL or #AGPL enforcement), a universal principle in #copyleft enforcement is always to use litigation as a last resort. Take a look at SFC's #baltobu project; we want to get working solutions to users ASAP:

The most comprehensive & detailed article yet covering the situation with Bambu Lab's violations of AGPLv3 in their Bambu Studio product, & my & SFC's work to do something about it.
If you're able,please donate to SFC's fundraiser for this. I'm working 12-14 hours a day to keep up & could use help! https://sfc.ngo/sustainer

Hardliner here: I think the FOSS community should use #copyleft licenses instead of permissive licenses surrendering all their leverage, resulting in structural sustainability issues. And I think the FOSS community should not use centralized platforms such as #GitHub, #Jira, #Discord and X/Twitter, but use decentralized/local platforms instead to prevent #enshittification.
I wrote about these and other sustainability issues in this EC report:

Hey #lawFedi:
How many ways besides libel can a false statement, whether on its own, or in combination with something else, be made to constitute civil or criminal offence? (What suffices to constitute fraud? negligent misrepresentation? breach of contract or warranty? tortuous interference? perjury? etc.…?)
Suppose a rudimentary open-source #DRM were to be implemented in web servers and web browsers (or a web-browser add-on), such that the key to the TPM comprises proof of the user's agreement to and utterance of legal statements to the effect that they're not using "generative AI" (plagiarism synthesis) to interact with the site, will not use it during that interaction, and will not allow any #genAI software to access information from it or disclose that information to any entity that would? Suppose the ToS for the site were to require that perfunctory DRM.
Would there be a way to exploit #DMCA1201 and/or the #CFAA to make it an offence (whether a crime, or a viable cause to sue) to bypass that DRM in order to interact with the website?
Maybe @lessig or #EbenMoglen (anyone know him?) could draft something, to do to AI, through inversion of intent of those laws, as #copyleft to #copyright?
@mgeist Would those laws correspond approximately to CMA §41 and to §342 of the Criminal Code?
Yes, ∃ much gossip in the #3dprinting community that #Bambu is not only sponsoring many YouTubers, but also they appear to be one of the few companies that is moderation control of their own fora on 3ʳᵈ-party platforms such as reddit.
While I hope folks will chose a vendor that treats the community & their own customers better than #BambuLab does, #SFC has always been realistic about #copyleft violations: users already have devices & the deserve adjudication of their rights.

#Disturbing that Bambu behaved this way. They're ≈37% of #3Dprinting market. My discussions w/ experts indicate that Bambu leapfrogged *precisely* b/c they violate #AGPLv3.
#baltobu initiative is a sprint right now, but in the next few weeks, it'll become a marathon. It will take us time, but we will liberate the users' right to repair that #Bambu took away.
Software Freedom Conservancy (“SFC”) announces a new initiative regarding the software right to repair for users and consumers of 3D printers manufactured by Bambu Lab. After recent news of violations of the Affero General Public License, version 3 (“AGPLv3”), SFC staff began a comprehensive AGPLv3 compliance investigation of both the userspace software and firmware on Bambu's devices. While the investigation is ongoing, two specific AGPLv3 violations have been confirmed.

La mia piccola review del libro 'L'Autore artificiale' è stata abbastanza garbata da far parlare l'autore sul suo blog e su Linkedin. Include la sua traduzione italiana della recensione per chi non ha molta familiarità con la lingua della perfida Albione.
I've frankly been waiting years to use the word “truthiness” accurately re: issues related to #copyleft violations!
I got to do so in that article in the OP!
My SFC colleagues didn't insist on editing it out as off-topic. 😆
For those that don't know the term, “truthiness” is briefly defined in the article.
I also just found¹ #Colbert's old show where he 1ˢᵗ described it:

¹ Old Comedy Central stuff is so hard to find.
Yesterday, I published an article on some of the rights that you can exercise in software freedom *even if* your upstream has violated the #copyleft license. While their violation *will* limit your options, ∃ many useful activities that you still have rights to pursue.

While recent events inspired this, other situations are similar.
IANAL & TINLA.

Years ago, copyleft violations were often a mere misunderstanding; vendors intended to comply but made mistakes. In those “before times”, a simple request and short discussion often led to the complete, Corresponding Source (“CCS”) for the the distributed binary works (or, in the case of network-service copyleft, the deployed systems).
