Makes you REALLY confident in Adobe Activation servers (and activation servers in general!!!)

^ yes, there is a certain amount of uncertainty even there.

Also, I was wondering had they delayed uploading the remaining titles because they were looking to find a more secure way of doing it. Or maybe it's just incompetence...

It looks like Adobe have updated the page, adding a message of clarification about the policy:

The serial numbers below should only be used by customers who legitimately purchased CS2 or Acrobat 7 and need to maintain their current use of these products.

At the same time they've removed Acrobat Pro 8 and Photoshop Elements 5.0 from the list and added After Effects. There must be a reason...

I think Carol has it correct. They're looking the other way because it isn't worth forcing the issue. And if it does become an issue they still have legal recourse if necessary.

When Microsoft was attempting to establish Office as the de facto productivity suite they overlooked a great deal of the casual piracy taking place. Once Office was established; and WordPerfect, Lotus, Harvard Graphics, Smart, and other rivals were safely out of the way, Microsoft started getting serious about their licensing by introducing a much more real activation program that included Genuine Advantage. As some competitors pointed out back then, how can you compete when Office is effectively free?

I think a little of that is also in Adobe's strategy.
