It's both. I was part of many conversations starting around ~2005 or so where business owners wanted to convert to a subscription model to prevent piracy. You see it everywhere now.
Surely it's that they would rather have steady income by the month rather than an unpredictable glut that follows the release?
I was part of that piracy wave, but now think things should get paid for.
