I stand corrected, it is not free at all. That link is only for owners of CS2 and an error was made. They made that very clear all over the forums two days ago. This is a false rumor and those downloading and installing are technically stealing it seems.

Since I own more recent versions it does not matter to me, but thought I'd correct the misunderstanding so people don't accidentally do something dishonest, not realizing they were pirating software.
