As technologists I think it's tempting to believe that decentralization can be achieved if we just had the right tech – better interfaces, more options, the right algorithms, whatever. I've been guilty of this myself; Pinafore is my attempt to make Mastodon's UI more accessible. But Doctorow makes a good case that these are just band-aids on what is fundamentally a policy problem. And unfortunately the policy solutions being floated right now would entrench monopolies rather than break them up.
