CC has been out a good long while now and has not been cracked. I'm not saying it can't be done but I don't think its nearly as easy as many people think. CS6 will have to serve you a good long time it still pretty darn good after all.
While this is true, perhaps the hackers have been cracking the CS6 perpetual license versions instead. While ever cracked versions of the latest (CS6) versions are around there is no need to crack CC.
However, once CS6 becomes out of date they will inevitably focus their efforts on the latest versions, which will mean CC.
Is it trivial? I don't know. It's it doable? I would think so. There are some very talented hackers out there who do it for the pride and enjoyment, not for the money.
However, my biggest fear with using hacked products is that having hacked them to remove copy protection and/or subscription systems, what other (malicious) systems could they have installed instead, like key loggers and other such systems. There are plenty of talented hackers who crack software for exactly this reason.
Apart from the ethical problems (why is the main reason I pay for the software I use) there are these obvious security problems which would scare the hell out of me. So I'll be sticking with official software, even if it's down rev.
