The computer fraud and abuse act could also be applied for criminal charges -- Adobe misused and misappropriated their access to customer data and systems. Arguing that it was a "mistake" and "we are sorry" does not correct the damage done. If Adobe makes such a fuss over protecting their IP, then they should not be surprised when their customers do so also. There is a potential for a class action here as well. And Adobe is very profitable -- some legal team representing this case, even if pro bono, will be/become quite rich.
Moreover, telling people that they should have X, and Y, and Z, to protect themselves from the mistakes of rogue actors/apps, is simply a displacement of responsibility tactic.
Just because something illegal/damaging was "done with a computer" does not mean it was "ok" and "an apology is enough" -- now pay us for our services you miserable worm/user!
