A few ways folks could look at this. The dark side (cue Vader breathing) would tell you that they are 'hurting' in sales and it is a gimmick to get folks to be interested in the game. There may be some validity to that, but I don't think it is the primary motivation from Privateer Press.
My view is that putting the rules out there, complete, but not in the most optimal viewing format, gives people the a great chance to look at the rules and get excited. My guess is that they will only loose about 1-5% of sales from folks that are too cheap to buy the books as many of the loyal players will still want a nice, full color, bounded, heavy graphics version for themselves. I think this moves give Privateer a great way to connect with their fan base.
On the flip side, they have thrown out the lawyers on the stat cards. I see the fear here on their part, but to be honest, if nobody is selling them, then it shouldn't impact sales too badly. I don't think the lawyers need to get involved honestly as long as the IP is not being sold.
Love these IP discussions? I would recommend reading techdirt. They have a great writer that covers modern media issues as they relate to privacy and intellectual property. Good reading that is usually on my list every day.
