You did see that article is from a year ago?

The two directions that Adobe and Corel have taken are not the same. It is yet to be seen whether Corel will keep to its stated commitment to perpetual licensing. CorelDraw's 6.3 and 6.4 update have brought a couple items into CD that were premium subscription only at the time of that article's writing.

When CS6 came out, and along with it CC, Adobe announced that all the changes in the CC version of the application would be rolled into CS7 (perpetual license) version. That of course did not happen. Time will tell if Corel follows the same path or not. I think for Corel it would be a true death knell. Adobe is far larger, all of its revenue doesn't come from software. I think Adobe can get away with such a move (at least in the near term) whereas for Corel it would be the end.
