> Many people won't touch GPL derivatives for their business / side-project-that-might-turn-into-a-business so such a license can have an inhibiting effect in adoption. Developers generally aren't stupid, they know that and they choose more permissive licenses, because they want to be seen, they want their solution to be used. They maybe want the fame and open doors associated with having such a project take off. It is a trade-off under their control.

It's a race to the bottom, largely because developers aren't unionized. Developers who would do work under the GPL get undercut by those who are willing to do it for free.
