UPDATE, 2:40 p.m. PT: There has been clarification since this story broke. Adobe has not released the CS2 software for free. Instead, it has cancelled its CS2 license management servers, so for those with existing licenses it is now offering downloads that do not require contact with the licensing servers. This service is only going to be available for those with existing Adobe CS2 licenses, which will be verified when creating the Adobe account to download the software.
Unfortunately sources that are normally very reliable were wrong on this occasion.
