People keep saying that one of the reasons Adobe is doing this is to combat piracy. Yeah, right. If anyone, at Adobe or elsewhere, thinks this is actually going to stop piracy, or even have a noticeable impact on it, then LOL... that's all I have to say.
I would venture that it will actually increase piracy, as more people will feel justified to flip Adobe the bird... hard to inspire loyalty when your customers see your new pricing scheme as a cash grab.
