Yes, this is all addressed in my blog post, including the points where there are the most major re-centralization risks of fediverse.

As for the overall situation you can compare with road traffic. Post-facto interop is something like "if my car fits through here, then that's my shortcut", and over time it becomes a busy crossroad point. Is it safe? No. Responsible? No, unsuspecting pedestrians are killed by cars speeding from unexpected directions? Is it efficient? Not at all, all traffic is stuck, everyone honking their horns. The law of the strongest rules supreme: Big SUV's and careless drivers have the advantage. Traffic is like this in some countries. People get used to it, and things become streamlined to an extent in this chaos. But it is far from optimal.
Now take the US as example. Totally car-optimized (app-centric). To the extent it isolates people even.
Interesting paper, thanks. I just made an analogy to how road networks evolve over time, and what that means for the #social environment. This against the backdrop of my long blog article about #ActivityPub fediverse #evolution.

Social experience design examines the #SocioCultural ecosystem that emerges by the #technology landscape and is determined by the shape of our #tech that it must grown on. Think like organic moss, that is able to take a foothold in the nooks and crannies of slick aluminium roofs. #SocialWeb is a forest.
An observation is that we generally severely underestimate the impact of "adding an extra online channel, so now we can be social remotely". This way of perceiving social totally misses how everything is different online, and at the same time that many things should / can be very similar to how we do offline #SocialNetworking for ages. Increasing social bandwidth on the wire.
