It looks like they wanted to kill most of the reverse engineering by cutting down on low effort recomps. It had got to the point where people who knew nothing of coding were recompiling major games just by throwing tokens at it. I'm neither condemning nor supporting it, just reporting.

Someone on Reddit made a good point. Even a short fence stops most people from treading on your lawn.

In other words, people who try to divide and conquer recompilations will likely still succeed... for now.
