We can use RSS/Atom with smart contract to distribute the ADA when new content is available. To be sure this not being exploited, we can give the power to get back ADA to the audience. We can charge a small fee to keep our infrastructure, but as the code is opensource, anyone can host a server to cut costs.
Creators and influencers will be motivated to create more content on website, podcast, docs, blogs, social media, and more without being canceled by platforms and corporations. The audience will be happy that some of the money isn't being used by someone other than their favorite creator.
Of course, this mean that if some creator audience does not agree with the creator speech, a boycott can be made, but in this case, it's the audience doing it, not the platform by some obscure criteria.
RSS/Atom are already descentralized. Blockchain is descentralized. To run the contract and fetch updates from the feed We'll need to have some kind of processing and hosting service, if we have a service then we have infrastructure costs and a point of centralization. We have some tools to handle this like IPFS, handshake and more. But this is beyond the MVP scope, right now I think the blockchain descentralization is enough to attract the creators.
We still need to define legal aspects. As we'll have a centralized part in this beginning, we'll need to be protected. Regarding the centralized part, we can use the MVP to strict the rules and fine tune the system around it to accepted levels of governance. For example: If someone wants to receive sponsorship for something illegal, it is our right as a company to choose to deny access to their contract, and remove it from our platform. This one would fork the project, build his own rules and infrastructure, put his contract there and be visible again (actually he never lost his visibility, everything required to do the transaction is in the blockchain, the centralized part just facilitates that).
