Yeah, this whole "We'll open it up later if something forces us to shut down authentication" is bogus. Think about a situation like this one.
Company A is bought by Company B and Company B orders authentication servers formerly run by Company A to be shut off. Even if some do-gooder coder there decides the right thing to do is to develop something on his or her own time that takes away the tether on their previous games and releases it on behalf of Company A then leaves the company, I would think Company B would probably end up suing him or her to kingdom come.
