it's probably worth noting that this indictment goes out of its way to specify that the campaign officials these entities communicated with were "unwitting" participants, and the indicted parties were posing as americans.

The Deputy AG was questioned about this at his brief presser. He was very careful in his response saying "...this indictment makes no accusations..."

He refused to comment outside of this particular indictment which is rather narrow in scope relative to the investigation, and had no comment from the special counsel.

Correct, though I'm not sure if that means this represents all connections the Trump campaign may have had with Russians that the SC has found (that we didn't know about previously, e.g. Manafort in Ukraine).
