From reading that, it looks like they are doing something similar to Medium. They are charging users for access, then the network pays out some of that fee to content providers.
The difference with this approach is that users have paid to view the content. With the safe network, users can always browse for free, with no restrictions (throttling, etc). There is also no portal (like skynet) on safe network.
Economically, this closes the loop. Users pay indirectly for premium content, just like Medium. There is nothing wrong with this model and I think it works well on Medium. However, it is quite different economically for PtP on safe network.
I do think this sort of thing could work at the app level on safe network though. Paying a monthly fee (like skynet, Medium, etc) to access premium content, which can then be used indirectly as rewards for popular content can work well. It just isn’t really PtP as we are discussing on this thread.
