But isn't chess one subset within that network, which would indeed be covered by any law regulating addictiveness of social media? Or will you allow people to be caught up on their own "otaku" like obsession with whatever niche area, but it is simply verboten to notify them of the existence of a different niche?

I also don't see how people can separate "optimizing addictiveness" (e.g. making your junk food too yummy or whatever) versus simply trying to make a better product that gives your customers what they want. The main criteria for who gets described in this way seems to be the corporate structure of the seller.
