It seems like Adobe is offering free versions of CS2. But ad they corrected on the blog:
You have heard wrong! Adobe is absolutely not providing free copies of CS2!
What is true is that Adobe is terminating the activation servers for CS2 and that for existing licensed users of CS2 who need to reinstall their software, copies of CS2 that don’t require activation but do require valid serial numbers are available. (Special serial numbers are provided on the page for each product download.)
Anyway, if you go to this page what you will find is the creative suite. If you have a digital creative streak but your budget doesn’t extend far enough to buy Adobe’s Creative Suite applications, this is for you.
