I understand the sentiment and agree with the diagnosis. I just worry that the proposed cure won't address the illness. Decentralization is a band-aid at best.
I think the traditional journalism business model is just a proxy for "truth" in the sense that fact-checking and reliability is really what's at stake versus social media "news." And the substituted point is still valid - truth as a business model is no longer financially viable - but the cure I feel should be to make truth financially viable. One way to do that is to depress demand for misinformation (laws prohibiting misinformation and enforcement, creating boycott campaigns against platforms that algorithmically incentivize misinformation like Facebook and X). The other is to reward truth (educate the populace to support it, sure, but also keep funding as a social good journalism like NPR, PBS).
It's not great, but I don't feel just pushing into decentralized media will do anything except create even more competing "truths" and hasten information exhaustion. That path leads to Russia, where the populace seems mostly nihilistic and too jaded to act.
Do you have logs or software that keeps track of what you need to redownload? A big stress for me with that method is remembering or keeping track of what is lost when I and software can't even see the filesystem anymore.
