"And when you have 10 [P2P] groups with [small number of family, friends, etc.] in each, then people will share to them pretty freely [in each case, only the content that is warranted for those individual groups]."

...

It's not possible in iMessage - with end-to-end encryption, Apple has no idea what you're sharing."

[ There is no technicological reason that one company, or any company, needs to have control over the management of these "groups" and the "messaging" that may occur within them.

Two "groups" communicating over internet need not be connected in any way, bridging them is an option that should be left for the user. For example, each group is reachable only via a separate network interface. Not "networks" or "interfaces" as defined by marketing copy and buzzwords, but traditional network interfaces defined by software. The type of interfaces displayed when a user types "ifconfig" and "ipconfig /all".

The interface used to "surf the web", the one that connects to the sewer of advertising that is todays web, is the not same one used to reach any group. Think of this like VLANs if you wish but its even simpler. I have been "beta-testing" such a system, which is not new, for many years. Theres no ads, no spam, no BS. It works. The "intelligence" of the network, so to speak, is at the edge, with the user.

Theres no money in this, necessarily. This isnt an elevator pitch. Its called "a private life". Everyone needs one. The whole point is to escape the commercial world for a little while. "Clean separation", like those network interfaces. ]
