It’s very interesting and telling that most of the technology that connects us does not have us as a customer, or a financial beneficiary. One of the key aspects of technofeudalism is the extractive nature of most of our platforms.
I'm just thankful that mobile phone networks haven't switched to a "free with ads interspersed into your texts" model yet.
(Of course there are still ads in my texts, but at least those are officially spam rather than network endorsed.)
I know some very privacy-focused person (a friend of mine) who will stop being willing to be in contact with you (or being your friend) if you use an email address at one of these big spying email providers to write him an email.
So, it is just a matter of being consequential.
It was an X.400-based nightmare, and never took off.
Market timing is hard.
Literally in a span of months SMS usage went the way of the dinosaur.
