In no particular order of stupidity:
1. Wizards has stopped PDF sales DESPITE the fact that the existing security process allowed them to identify the sources of the pirated materials... um, so that they can have time to come up with a security system that would let them, um, identify the source of pirated materials.
2. This relates to fewer than 3,000 copies. The legal fees alone would have already exceeded the total revenue (and not profit) of 3,000 sales at MRRP!
3. For the sake of 3,000 copies that probably had no impact on Wizards' revenues (or profits), Wizards has unleashed an Epic-level spell of nerdrageacross the internet doing untold damage to the brand with those of us who actually buy their products.
No business should be run by its lawyers. And I say that as someone who likes lawyers, who has close friends and business partners who are lawyers, but that doesn't mean that I let them run the commercial side of my businesses (just as I don't run the legal side of my businesses).
However, I do wish I was a lawyer for Wizards and/or Hasbro because I can see now that they would be an easy mark for squeezing out some ridiculous fees to fund multiple tilts at multiple small windmills.
If Wizards has a CEO who is worth his pay he should be stepping in right now and providing some real leadership.
