If they don't survive in their current incarnation, they'll likely pivot to something else like curation with smartsteem
I don't know how to answer what the point is for having them as I don't support them. They're a product of the market. If they're profitable, they'll exist, if not, they wont'. I'd like to see the latter because I think it's better for the entire ecosystem.
