I already showed you a federal trial of other Russians who cracked Adobe. Take your claims it was unconstitutional up with the judge.
They were selling the cracking software: "for profit" requirement met.
They admitted they knew about the DMCA: "willful" requirement met.
On second thought, now that you provided the Adobe C&D, you can say that their infringement was willful for the time after the letter (assuming the letter actually got to the hackers, as it was not sent directly to them). However, the article still shows not a hint of them doing it for financial gain. Both are required by law.
The obvious unconstitutionality, stupidity, and downright unfairness to the public of the DMCA is an entirely different matter. I can explain that if you'd like.
