It's a little like we've gone back to the problem of the customer becoming the product.

If I were a mathematician I would not my unpublished work to go into the hands of a competitor.

If I were a lawyer I wouldn't want private details of my defense to be made available to the prosecution. Anonymous or otherwise.

I wouldn't want the plot to an unreleased book to be suggested to another author.

If I were a business, I wouldn't want my proprietary business information into a hands of a competitor. But CEOs are racing to do it, and (at best) relying in flimsy contractual guarantees they have no means to verify.
