Postel's Law: The Open Source Evolutionary Dead End
2025-03-27
Postel's Law, advocating "be conservative in what you do, be liberal in what you accept," has ironically led to an evolutionary dead end for open-source software. Because closed-source producers often violate specifications, open-source consumers are forced to constantly compromise, leading to specifications becoming meaningless, hindering new projects, and reducing competitiveness. The author urges open-source maintainers to strictly adhere to specifications, reject unreasonable user requests, and direct issues to the offending closed-source vendors, avoiding the "three-ring circus" and maintaining specification integrity.
