It's striking that no consideration is given in these recommendations to changing the network or ownership structures. Like moving to an inter-connected network of independent social media communities.

True, these comments were made in 2019 - 4 years ago - when even fewer people had heard of the fediverse, or Mastodon. But that year, while living in China, I was at the #Netizen21 conference:

I'll try to provide some running commentary on the conference in the 'verse, like I did for the #Netizen21 conference in Hangzhou, China.
Some of your may have caught some of my live-posting from the #Netizen21 conference, which was hosted by INS.
I was too busy live-posting here or scratching down notes to notice, but my wife was fascinated to watch the way #Slido was being used at #Netizen21. A lot of the audience were using it during the talks to share their thoughts about what the speakers were talking about, and upvoting each others' comments. This is similar to the way I imagined #Loomio being used at #OpenSourceOpenSociety back in 2015. Except that Loomio would make it easier to keep those conversations going after the event.
The Young Scholars forum at #Netizen21 took up day #1 of the conference and the fourth panel is finishing up day #3, also focusing on Platform Capitalism.

The third panel at #Netizen21, is called 'Media Archaeology'. I really wish I could understand Chinese because all three of the panels today had fascinating topics. Mind you, even if I had been studiously working on my #Mandarin skills since before we got here, I imagine I'd still be struggling to follow academic lectures ;)
A lot more people in the audience for this session of #Netizen21 than there were this morning.
