Comparing what Stardock is doing with Activation to Sony's hidden issues is a bit off base.
The only person who would lose would be the one who does not own the product key (serial number), as it should be.
Stardock has the records of who owns which keys, and can verify this information if anyone runs into an issue.
If I am not mistaken, Stardock can send you a file to place in your sub-directory to activate the product if you contact them via e-mail.
