I deal with this by subscribing to very few mainstream media sources since they typically report the same thing in unison with slight variation. The slight variation makes deduplication technically difficult. I use Nextcloud News, and maybe their future LLM models could accomplish this.

I have a similar 321 strategy without using someone else's server and needing to traverse the internet. I keep my drive in the pool shed, since if my house was to blow up or get robbed, the shed would probably be fine.
