by law, Adobe is required to send WRITTEN NOTICE to every single customer w/ private information that they have. Regardless if they are in data breach or not. Which will cost millions in postage. Who wants to be Big Business won't do it and nobody will hold them accountable?
I received a notice concerning this in the mail from Adobe, so yes, they are sending these notices out. I have been in an ongoing process of purging my accounts of simple passwords, and had changed my Adobe password on 8/31. Unfortunately, that is likely after the data breach occurred, so it is possible that they have one of my old, simple passwords that I used all over the place. What a headache.
