The discussion revolves around the experiences of communicating with the Free Software Foundation (FSF) via postal mail as stipulated in GPL v2 licenses. Commenters share insights about the decline in postal communication relevance, particularly among younger tech users, which raises questions about how these traditional methods affect compliance. One user recounts a previous experience where an invalid address led to a significant operational challenge, enforcing the need for manual verification methods beyond automated testing processes. Several comments also reflect on international differences in postal practices, particularly regarding paper sizes and the general understanding of postal systems in tech communities. Ultimately, the conversation highlights the importance of maintaining valid contact methods outlined in licenses and the evolution of communication methods in the tech industry.
