I think you are right the 50-50 split is fair.
But maybe the non native tax rise is a good thing and would create an incentive to authors to use the #pob front end more.
I am all for reducing native taxes in exchange for upping non native taxes.
This would benefit the community, although I dont think reducing native to 0 would be a good thing for the community as it may not bring in enough taxes at first for maintanence costs etc,maybe a 5-15 split which seems fair and ensure income through taxes for maintenence.
With the tax taken before a 50-50 split between author and curator becoming equal or are there other reasons, why the 50-50 isint done equally
