Sadly, I don't think Adobe is alone on the "hey, did you miss the 6 month beta period?" wagon. I recall many instances of software breaking horribly after an OS update.
Yes, the beta run of Lion was shorter than others, but this isn't the first time something like this has happened with a major developer's software.
Did anybody see a smoking gun that suggests ill intent? I missed it. Does anything point to anything but regression?
