Ordinarily, publishing things grants you rewards on the order of the global significance of your work, as measured by its impact on the world of scientific papers. Should he be able to reap greater rewards by targeting the measure instead? (As the GM of a real world science game, I'd allow it, cause it's a neat idea. But if we actually try to refer to the global significance of your work...) This copyright stuff, evil as it may be in the general case, does seem to avert this kind of going meta.

Of course, the real solution in this case is for him to anonymously publish that list of errors along with a hash value whose input he keeps to himself until legislation would have allowed him to non-anonymously publish the list. Optimal number of future citations (even better than if he simply waited for the legislation!) and optimal actual betterment of the world.
