I'm confused. It seems you have more information than the blog post and attached documents entail.

Do you know both how long the investigation would be under for? Do you know the timing?

Stating there's no good reason is not true - it's quite possible that a gag order is issued to protect the investigation, including identification of suspects, the number of suspects (at least two in this case), change of behavior (e.g. switch from Signal to smoke signals, fax, or just lay low for a while), etc.

What happens when two days after a terrorist attack, OWS publishes a subpoena for the first time? I for one welcome that they go through the official channels to get the redacted version approved. Let's not botch investigations for the sake of pitchforking the "everything should be public" slogans.

I think a middle ground is possible in this specific case. The government could have said "we're placing a selective gag order, meaning you can't publish this notice but you can publish the redacted notice that we've helpfully attached", rather than wait for OWS to file a petition to publish the redacted version.
