It depends upon the business model of the app, and how they generate their revenue. Perhaps people have to prove that they looked at some advertising. It could even be a paid-for app, which uses the Safe Network (perhaps behind the scenes), and as part of the package they give ‘free’ Safecoins. (Feel free to quibble with my use of the word free).
How about apps like the Civic one?
This is not very tastefull, but someone could set up a gateway whereby people are paid small amounts of Safecoin in exchange for paying attention to some advertising.
Are people aware of BAT? Basic Attention Token. The intention was to integrate this into the Brave browser (and others down the line). It reorganises the advertising model, partly so that consumers get paid for their attention to advertising. Could we have two versions of the Safe Browser? Bastardise one of them so that people get paid in Safecoin in exchange for proving that they have paid attention to some advertising. Once they have accumulated some Safecoin they can upgrade to the advertising-free Safe Browser.
People can decide what they want to do. Pay for Safecoin with some kind of money (directly or indirectly), or pay for it by exposing themselves to advertising.
I know this is not ideal - I’d prefer it if we could solve the problem in another way really…
Edit: will people really have to do one last ‘dance with the devil’ in some way just to be able to gain un-gameable access to the Safe Network?
