This isn't exactly right. Part of the debate was that Twitter is the platform and the platform should not censor. This left Trump without any authoritative criticism other than the sea of response tweets. In a decentralized systems, you would have many platform providers, many decentralized features and also many filters. In a decentralized system, the filtering/curating holds less ethical baggage (ie just choose another filter you like more!). Curators are free to curate more heavily. If there was one single email platform, every spam marking would be a political and ethical hill to die on. Instead its a non-issue.
