If this post is true a lot more of the people who matter should be caring once they become aware and if they don't them the people who need confidentiality should. We'll see how the cards fall.
Confidentiality agreements REALLY mater to big companies. Once they're made aware that Adobe does this they'll either kick up a fuss so Adobe won't do it to them or switch programs. We've already seen people break Ai in plenty of ways, I wouldn't out it past people to figure out how to break the Adobe one to show original artwork for confidential projects at some point. We'll see how it goes.
