Ed Felten has more sound thoughts on the latest Sony drm security patch hole.
"Security is all about risk management. If you’re careful to avoid unnecessary risks, to manage the risks you must accept, and to have a recovery plan for when things go wrong, you can keep your security under control. If you plunge ahead, heedless of the risks, you’ll be sorry.
If you’re a parent, you’ll surely remember the time your kid left an overfull glass of juice on the corner of a table and, after the inevitable spill, said, “It was an accident. It’s not my fault.” And so the kid had to learn why we don’t set glasses at the very edges of tables, or balance paintbrushes on the top of the easel, or leave roller skates on the stairs. The accident won’t happen every time, or even most of the time, but it will happen eventually.
If you’re a software vendor, your software creates risks for its users, and you have a responsibility to your customers to help them manage those risks. You should help your customers make informed choices about when and how to use your software, and you should design your software to avoid exposing customers to unnecessary risks."
Felten's DRM, Incompatibility, and Market Power: A Visit to the Sausage Factory is also a must read on this sorry saga.
