I live in the United States. The DMCA and similar laws apply to me, and even innocent and morally permissible software development practices can be illegal. Specifically, anything that involves disabling or interfering with DRM is prohibited.
While criminal charges are unlikely (but not unheard of), civil litigation is certainly possible and is often somewhat misaimed. Various legal theories advanced by lawyers who push this litigation include concepts like "contributory infringement" make it so that even forums where such things are discussed can be attacked.
Is it permissible here to discuss "cracking" software, disabling DRM, or similar activities? Are there guidelines for how much and what should be said? Should specific software titles or product models/brands be left out? Are these questions only allowed if the questioner is doing it for personal use, do you discourage someone who will release their project to the public?
