Industry secrets are a freely-chosen alternative to IP; they're not the same as IP. Proper IP protection requires disclosure and is either time-limited (wrt. copyrights and patents) or constrained so as not to impede competition (trademarks). When IP is extended beyond these boundaries, it becomes wrong and a severe drag on economic growth. Such as when IP-related laws are used to impinge on fair dealing, fair use and first-sale rights, e.g. by enforcing oppressive DRM.
