wouldn’t it be the funniest fucking thing ever (albiet impossible) if the mozilla foundation somehow raised the funds through maybe some kind of crowdfunding or something and bought only to proceed to dump it directly into the public domain.

This isn’t a “win”. The “win” happens in court.

Most of this stuff the DOJ pushes doesn’t happen. And while it’s a “decision” in the case of deciding the policy stance of the department, using the word decision in a legal context implies a court ruling that actually (barring appeals) makes things happen. This is at best a hope, and you’re relying on the Trump DOJ to actually pursue it.
