Privacy strikes (again!)

Events unfold thus:
  • Netflix releases data for a stunning contest that captures the researchers' imagination.
  • Researchers correlate the data with publically available data to break anonymity. Netflix is sued.
  • Legalese, yaada, yaada, yaada ... Netflix cancels the version 2 of the contest.

Why can't they just implement some kind of opt in system to release training data? They could even still keep the unreleased data as test data.

I guess there might be some issues with introducing sampling bias into the data, but I doubt its worth killing the contest over.
