I don't know. If porn was open source, you'd get access to the script, you would have insight into the the number of cameras they use, how they chose the clothes they used in the movie, how much everyone on the team is contributing to the end product. Every time someoke has a cool idea for improvements and the skills to submit a PR, you'd download the thing again just to find out that the thibg doesn't fit into the thing anymore and everybody would be discussing where the error might be and who's responsible for fixing the thing. I like my porn not to be open source, sounds pretty boring for sex. FOSS is pretty cool, though.
