One of the reasons the standard open-sources licenses such as the GPL and the permissive licenses are as popular as they are is the lowness of the probability that lawyers will ever be involved.
There was widespread use of GPL software in the 1980s and early 1990s for about 15 years IIRC before the first lawsuit involving GPLed software.
