[Question] Why Don’t Creators Switch to their Own Platforms?

Al­most ev­ery con­tent cre­ator ra­tio­nal­ists fol­low owns their plat­form: pod­cast­ers like Sam Har­ris and the Ju­lia Galef, blog­gers like Scott (and my­self), all the nerdy we­b­comics. And yet, out­side the ra­tio­nal­sphere ev­ery cre­ator seems en­gaged in an end­less fight against cen­sor­ship and ha­rass­ment by the plat­forms that are sup­posed to en­able them: Face­book, Twit­ter, Tum­blr, Pa­treon… So why do they stay on those plat­forms? Other than Sam Har­ris giv­ing Pa­treon the mid­dle finger, no one else seems to do much ex­cept protest plat­forms on the plat­forms them­selves.

This ques­tions re­ally came up for me af­ter read­ing the saga of Pewdiepie and YouTube. Cur­rently, pewdiepie.com redi­rects to his YouTube page, where he posts videos protest­ing YouTube. This is crazy. The tech­nol­ogy that YouTube pro­vides was hard to build when YouTube started a decade and a half ago, but surely to­day it’s not a huge challenge. PDP has 20 billion to­tal views. He doesn’t need traf­fic from the al­gorithm sug­gest­ing his videos, ev­ery­one else is try­ing to game the al­gorithm to get redi­rected by PDP! Switch­ing to his own plat­form would al­low him to cap­ture a higher per­centage of rev­enue, be im­mune to any kind of cen­sor­ship, and make him a leg­end if he starts an ex­o­dus from YouTube. He can host all the other non-PC co­me­di­ans on his own plat­form. How is that not worth los­ing a bit of traf­fic as view­ers read­just?
