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

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.

The conflict between Bambu Lab and the open-source community, led by the SFC and Josef Prusa, over alleged AGPLv3 violations in Bambu Studio is escalating. This isn't merely a software licensing debate; it's a pivotal moment for user rights, the 'right to repair,' and the future of open-source hardware, with real consequences for developers and consumers alike.

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).
