To combat software piracy, developers have implemented various digital rights management (DRM) measures, including encryption, watermarking, and online activation. These techniques aim to protect software products from unauthorized use and distribution. However, some argue that DRM measures can be overly restrictive, limiting legitimate users' freedom to use their software as they see fit. The "Noah 4 License Key" controversy highlights the ongoing struggle to balance the need to protect intellectual property with the need to ensure that legitimate users can access and utilize software products without undue restriction.
