No. That is historic DOJ, and most other prosecuting authorities, standard practice, for a multitude of reasons, mostly that it is unfair to a defendant to accuse them in public as opposed to the forum in which they can actually defend themselves.
Also, that indictment is really short on actual facts, compared to many we have seen recently. It cites a number of unnamed co-conspirators who no doubt supplied those facts under considerable inducement from the government.
Also, the particular section of the law in question, https://www.law.cornell.edu/uscode/text/8/1324, seems to encompass a lot of lawful conduct and may violate the 1st amendment (association):
knowing or in reckless disregard of the fact that an alien has come to, entered, or remains in the United States in violation of law, transports, or moves or attempts to transport or move such alien within the United States by means of transportation or otherwise, in furtherance of such violation of law;
I'm guessing the lawyer resigned because a) political b) entirely based on jailhouse informants and c) probably an unconsitutional or at least rarely-charged statute. Note that the "for profit" allegations of the indictment is not part of the charged crime.
Also, note that they didn't charge firearms offenses, but if true and provable, what was alleged in the indictment would support a pretty serious federal firearms charge.
