As you, DD, mouton and others have pointed out, there is more to support irreparable harm than the monetary damages even as diminished by the AG launch. I see that too.
Reasonable people may differ on this factor.
My sense is that the judge focused on the monetary damages of the delay - more so than I would have.
We will soon be past this discussion since the judge will either dissolve, modify or convert the injunctive relief to a PI.

It is astonishing what foolish things one can temporarily believe if one thinks too long alone ... where it is often impossible to bring one's ideas to a conclusive test either formal or experimental. J.M. Keynes
