Since I am convinced the only location where Paizo can thrive to the extent necessary to maintain the scale of current operations is in close orbit to the 500 ft gorilla, I conclude deciding to do otherwise must be rooted in pride and resentment.
Pride in thinking the Pathfinder brand is (much) stronger than it really is. Every dndish game that isn't D&D quickly ends up on dusty shelves. (Note: Pathfinder was not it's own game, it WAS D&D)
Resentment in harboring a grudge for WotC when the coldly rational choice would be to realize your nature as a parasite, essentially, and forget about past bad treatment and stay close to the host organism that nourishes you.
I hope that answers your question
