      For some context: I teach OS security. A big part of that is convincing my students that code isn't magical. If your code is in any way visible, people will figure out what your code does. Malware's not magic here. Nor is DRM. Nor is anti-cheat.

      The magic of DRM for online services is that you don't just need to figure out what it's doing, you need to figure out what it's doing within a recent period of time, since it's dynamically rotated and just-in-time server validated.

      This "recent period of time" means that: 1. You have a running cost for keeping your anti-DRM working. 2. Obfuscation and protection measures increase the running cost. People need to recoup that running cost, and thus increase the price they charge for the "abusive" action.

          This directly leads to outcomes like 1. the number of abusers diminishing; 2. malicious actors not targeting you because there are so many easier ways to make money. There are more market effects in play, but overall you'll find that these things do work in their specific niche.
