The problem with GAF Gold won't be collecting payments, although that does have potential to go sideways as well. The problem is that no one is going to buy it, if all you get to do is donate money to EviLore. Most places offer a "premium" experience, like early access to videos, the ability to customize and style your account (or others, SA style), and other incentives to go with an ad-free experience. Sure, a handful of people have expressed interest (without knowing the price). No one is clamoring for it, because it already exists (uBlock Origin).
What's baffling, though, is how no one seems to see through the facade that is the current mobile advertising scheme. That being, let every shit ad through while doing nothing about it to sweeten up that GAF Gold experience Q1ish. Either nobody sees it, or, more likely, nobody cares, because they're already ad blocking.
My guess is that the new system will be responsive and the current mobile GAF will be put out to pasture, and it will have aggressive advertising (and more of it).
