I don't think this is a great situation/course of action.

- Depending on your jurisdiction, you may break the law anyway and risk trouble. - By buying something that you don't actually use, you effectively donate to a for-profit entity. To me at least, that feels very wrong. Donating directly to the creator would be different but since DRM is involved, you probably pay a middleman. - Even worse: by paying for DRM-infested media, you encourage the use of DRM.
