UPDATE: Nope — the reports were wrong. Adobe says “You have heard wrong! Adobe is absolutely not providing free copies of CS2!” http://www.forbes.com/sites/adriankingsleyhughes/2013/01/07/download-adobe-cs2-applications-for-free/
It appears that Adobe is allowing Adobe registered users to download Adobe CS2 suite including Photoshop for free. I haven’t seen anything official from Adobe on this but I just logged on using my own account and it does appear that I would be able to download Adobe CS2 for free.
Here’s a link to the Adobe download site: https://www.adobe.com/cfusion/entitlement/index.cfm?e=cs2%5Fdownloads&loc=en
