I think that this is an important part of the future of the fediverse. News sites and the like have shitty poorly moderated comment sections that serve almost no purpose. They have the resources to sustain a large instance and like you said it lets them more easily monetize their work. It seems like wins all around if enough news outlets adopt it.

I think it would be pretty cool if I could subscribe to different CBC sections, and have it show up in my normal feeds, I think this would mitigate the biases that relying on news going viral creates without having to go to the cbc itself and scrape through it myself.
