The strength of Share Alike licenses
Networks having chosen Share Alike open licenses have an important spiral effect.
Their productions being often important and of quality (because they reached more easily the grade 2 of wealth, see SĂ©samath), they are regularly requested to exchange contents with other close or similar networks.
If these networks have chosen a more restrictive licence (Uncommercial for example) exchange is very difficult because productions of the "open" network (network 1) need to be used or adapted by "the less open" network (network 2) to be shared alike... which means under open licence ! Which forces the "less open network" (2) to make a choice:
- or I benefit from the wealth of the open network (1) but then I have to change my less open for the more open licence of network 1 ;
- or I don't want to change my licence and I look with envy and despair all the wealth I could have shared and the grade 3 wealth (those highly valuable) we could have created together ;-)
