omare32247195, Hello. In conclusion, there is no choice except for those who have purchased CS6 products now. As you know, policy changes during this period have prevented CC subscribers from using CS6 and have ended the download of the CS6 installer.
Let's be clear about it: it's not "likely" that you get an illegal CS6 copy - it's a 100% certainty. There is no way to get a legal CS6 copy now, except maybe through customer support (if you already have a serial number).
