You make an effort to contact the defended and bring the lawsuit to a judge. I don't think the court will grant the 13 billions judgement, that's a fantasy number but I don't think they will throw out the lawsuit either.
Ans since Anna's Archive won't show up in court Spotify will probably receive a default judgement which they can fold and shove up their ass.
They are probably going after companies affiliated with Anna's Archive next, like especially hosting providers.
It's not a particular support worthy company IMO https://www.theregister.com/2025/10/14/framework_linux_controversy/
If you want the devices for technical reasons, sure, but from moral standpoint they aren't better than the next tech company.
