(1) Empathy over the whole Dragon/Dungeon thingSo why did other sites, Paizo being one of them, experience a spike in 3e sales?
(2) More loyal fanbase than any other 3pp, and that fanbase wants to see the company succeed.
(3) Positioned itself as the bastion of 3e/OGL gaming, kind of a beacon for the dispossessed - and see (2) above.
(4) Paizo is the only company still putting out 3e-compatible material of any quality, so if you want new 3e-compatible material, they're the only game in town.
(5) While some may disagree, I don't see EN Publishing as a vital offshoot of ENW - this site is primarily a forum and review place. Paizo, OTOH, is first a merchant and only secondarily a forum.
I don't think there's much of a mystery here.
