Apache has for a long time had a claim that is rare (if not unique) in the software world: the best software, that is most popular, and is cheapest (i.e. free).
This form of open source is collaborative innovation, or what Eric von Hippel would call “user innovation.” But what about people who need to make money off of their IP?
There are a few good examples of valuable books available free online:
- von Hippel’s 2005 book Democratizing Innovation
- The best book on open source licenses, Larry Rosen’s Open Source Licensing
- A better-than-most book on the business of open source, Producing Open Source Software (recommended by a client)
So while you can’t say the best things in life are free, there are a few good things in life that are.
