D.C. Grand Jury Orders Reddit to Turn Over Data on Anonymous ICE Critic

This is a most excellent place for technology news and articles.
No, it's not volunteering, at least not anymore.
Subpoena is legal Latin for "under penalty," because noncompliance with a subpoena carries a penalty.
Originally, it was an information request from the feds, and Reddit refused. Then they escalated to getting a grand jury subpoena (which means they got a bunch of normal citizens to agree that the information was relevant to a criminal investigation), so now noncompliance carries a penalty.
Reddit notified the users, who hired their own lawyers, who are resisting the subpoena and will litigate it to where they need a judge to decide whether Reddit will have to turn the information over.
That's the process for these things, and we're a couple steps in already.
Subpoena to appear, not subpeona to give up info

This reporting says that the subpoena requires that Reddit produce the information and appear for a hearing.
