I really dislike this entire mentality so much. At what point did we go from a place where you have a diverse set of companies making good revenues and profits and serve their audiences well to this crappy model of everyone trying to be the next Instagram.
Adult content creators are probably going to get booted off at some point for 'ad-friendliness' despite the fact that they helped build most of it.
There are plenty of such sites. You don't hear about them in the Web Dev/Startup bubble because they're just getting on with life and their business model, not open-sourcing the latest JavaScript framework du jour.
If they did this they will end up like tumblr: in the oblivion. They have the luck to be profitable, differently from tumblr. Them pivoting to non porn would be a choice, not a necessity like tumblr
