“A Crash Course in Open Source Licensing"
summary
A practical walkthrough of how software licensing actually controls copying, modification and distribution: explains that copyright gives exclusive copying rights, distinguishes reading from copying, shows when running code is allowed, and why attribution and offering source (not just a binary) matter. Uses concrete scenarios — bulletin board printouts, flash drives, GitHub repos, contributor agreements, relicensing choices — and contrasts the effects of GPL vs Apache 2 style terms (copyleft obligations versus permissive sublicensing).
