Software License metric: [F] Free and Open Source, [P] Proprietary/Closed source
This metric can also be modeled as a continuous variable rather than a discrete variable. But let us stick to two values for simplicity.
Development model metric: ranges from extremely [C] Cathedral-type, .........., to extremely [B] Anarchism/Bazaar-type
FOSS proponents don't care about development model as long as it's FOSS.
Let [x][y] denote the Software License metric (x) and Development model metric (y) of a software project.
Observations:
1. [P][C] is the combination that FOSS proponents hate the most.
2. [x][B] where x ∈ {F, P}; is less peer-reviewed (anyone can commit anything), so less accountability/responsibility, highly decentralized, so no guarantee of quality.
2.1. [P][B] sounds like a contradiction!
2.2. [F][B] Poul-Henning Kamp seems to have problems with this kind of setups.
3. [F][y] where y -> B (i.e. closer to [B] than it's closer to [C]). Mostly same as [F][C] except that it is mildly better.
4. [F][C] In this setup, the cathedral authority is the bottleneck in improving the project.
5. [F][y] where y -> C (i.e. closer to [C] than it's closer to [B]). This kind of setup "works like a charm!" See the overall success of GNU/Linux in the industry! There are some people who act as maintainers of Linux, but come on, you too can become one! The more popular such a software is the more thoroughly it is reviewed. "Given enough eyeballs, all bugs are shallow."
