Organization chart of a network's life
Grade 1: the networks gets organized and compiles the contributions of its members.
Situation 1
OR members discuss the status of contributions of each and consciously choose to place their contributions in an open license (really open so unrestricted to commercial use - CN of Creatives Commons licenses -)
This implies that anyone who does not agree withdraws its contributions
Situation 2
OR this topic is not clearly discussed and individual contributions are placed under open licence but without the author-members being fully aware of it.
Situation 3
OR members prefer to protect their contributions by a more restrictive license (like Creative Commons license BY NC SA) and therefore no commercial use without permission of the author.
Grade 2: the network grows and produces collective works relying on wealth of grade 1 (the personal contributions of members). These productions are "rich" enough to initiate a financial valuation.
Situation 1
Thanks to open license, collective productions can easily be exploited even if certain members of the network are not present any more! Each having beforehand authorized the valuation of its contributions for the mention of its name and the preservation under open licence. This being also valid if a member of the network seizes grade 2 wealth and sells them... It is true that it will cause tensions within the network and that this membership might not last in the group ... ;-)
LIFE
Situation 2
One (or some) members seizes grade 2 productions and sell them.
Author-members feel cheated and try to prevent the sale... which is impossible because grade 1 productions are under open licence.
The networks blows up !
DEATH
Situation 3
The licence not being fully open, the network has to ask each member's (author) agreement for any commercial use of the production.
Most of the time, this step is so complicated that valuation crumbles down and the networks melts with the disappointment of not having experienced the interesting stage of a network (i.e. the collective production and the external valuation of it).
DANGER.... DEATH
