last-rights
Explanation
The comic features an older, bearded man (resembling a stereotypical open-source software advocate, possibly evoking figures like Richard Stallman) passionately declaring: "Open source is EVERYTHING. I will never stop pushing for it, even after I die!" His companion asks, "Wait what? What does that mean?"
The answer comes in the second panel, labeled "Later..." -- a gravestone reads: "HERE LIES STEVE. Contents of grave may be modified and used commercially without attribution."
The title "last-rights" is a triple pun. It refers to "last rites" (the religious ceremony performed before death), "rights" as in intellectual property rights, and the concept of rights/permissions in software licensing. The gravestone text parodies the language of permissive open-source licenses (like the MIT License or public domain dedications), which typically grant permission to use, modify, and distribute content freely and without attribution requirements.
The humor comes from the absurdity of applying software licensing concepts to one's own dead body. The character was so committed to open-source ideology that he extended it beyond code to his own mortal remains, essentially making his corpse "open source." There is also a darkly comic implication about what "modified and used commercially" might mean when applied to human remains.
