If sufficient people refrain from paying a subscription to the Creative Cloud, then it would make economic sense for Adobe to reinstate the status quo ante. Indeed it would be their only option. If enough people subscribe to the CC to equal or exceed the income Adobe were getting before, they are going to stay with the CC. It's pure math. Just as Microsoft are being forced to make changes to Windows 8 because of poor sales figures, Adobe will respond to financial pressure. So stay with whatever version of PS CS you have now; withhold your money!
