Adobe requested the lawsuit and was originally involved. Then they got picketed to hell, and after a month of pressure, they took their name off of the lawsuit.
The government continued prosecuting the case. Whether or not this was at Adobe's private request is an open question. Publically Adobe requested that the lawsuit be dropped.
Lemme google for some links.

In my books, Adobe does not get a free ride for having dropped out of the case that they requested be brought. If they establish a pattern of "good behaviour", then my opinion of them will change, but until I've been convinced that they are now against the DMCA etc, they remain grey at best in my books. Sometimes my interests align with theirs (they have no reason to like the dominance of Microsoft), and sometimes now (see comments about the DMCA).
Of course I doubt that they care much what I think. (Except in so far as I find myself in a position to recommend or not recommend their software.)
Cheers,
Ben
