Actually it's quite easy to imagine how they could have done so—although "changing their DRM" is probably the wrong way to think about it. They could simply change the seeds (garnered from user info) used to generate the keys (to the same DRM algorithm they've always used). User account info that registered apps and devices, of course, already know all about--and that Alf's plugin does not.
Or it's quite possible that there's always been multiple decryption/key schemes in the apps/devices that just weren't being used until now.
If it's the former—and it's based on account data that's publicly "knowable"—someone will probably come across the specific combination sooner, rather than later. If it's the latter (or keys are being generated from account tokens that users can't easily retrieve), it could spell trouble.
