Why not attack the Dual-License GPL model?

Mostly because this model leaves the power to circumvent a bad partner
in every developer's hands. The GPL does not contain any initial
developer grant. Instead, the initial developer depends on other parties
voluntarily entering into a copyright assignment or granting a right to
relicense. In general the initial developer will not accept code into
their own tree without that grant, but everyone is free to operate their
own tree which requires no such grant.
