What concrete action would you suggest to make the internet more democratic?
I am personally remiss in this matter as I thought deeply about all this when ICQ came out in mid 90s (and even filed a PPA on April 1st 1997 with USPTO on my take on the solution) but did not advocate effectively enough for the (obvious) architectural remedies. Frankly it bugs me to this day and weighs on me like a still born child.
Yes, there is need for user agents running on the user's devices. Your chrome browser transparently maintains a https connection to mother ship (last I checked). I don't think that part of it is really an issue.
Unless I am badly mistaken, you propose we tell people: "abandon all the services you've grown to like about the internet. Let's reboot the internet within the confines of this new secure service."
No sarcasm intended - a new service, with real security, would still lack a "killer app."
