They've given us a moderate amount of information: they've identified a problem (pirate pdfs) and the solution to the problem (no pdfs!). Unfortunately, as the solution is a bigger problem for us (no pdfs! Argh!), we need another solution. Well, we've been told that there might be a solution, but - alas - that's all. And we need more.
I'm willing to be somewhat patient, but if we haven't heard more in the next few days, there are a few people at Wizards who will need to be reeducated in the realities of the modern era.
I'd be willing to be patient if I was offered anything that even remotedly made sense as a reason. As it is I was either lied to, or - if WotC really did what they did for the reasons given - they are incredibly ignorant of the reality of today's internet and economy. I somehow doubt that the latter is the case.
