There is on issue, RSS is advert and cookie free. Meaning it creates a clean web, but as such prevents monetization, so I guess it was not suitable technology.
But on the other hand there are many blogs that do not care about Google Ads or similar, so it would be interesting to revamp RSS again.
I follow a few monetized feeds. They’re usually one of:
- One post per week, showcasing the sponsor
- Embedding a static image into every feed entry for their current sponsor
- Adding a text-based „this post is sponsored by“ sentence/paragraph to every post
