Back in 1989, some similarly "idealistic" folk released portions of Apple source code. At the time everyone wondered if this would be the end of Apples strategic advantage. The froup called itself Nu Prometheus and while they never released any other source the excesses that Apple took to (unsuccessfully?) track them down led almost directly to the creation of the EFF.

Not sure who wrote this but it seems fairly accurate to my memory of those days:

The reality though is that such source code is hardly ever a requirement to understanding or reverse engineering the underlying algorithm, and is likely already obsolete by the time it becomes public.
