There is Tor but that seems to overreach enough that I can’t really believe in it.
You mention tor. I don't thing its an accident. tor and the mixmaster has a lot in common in my eyes. Both use a model of 3 levels at the default (entry, mid and exit), both use a similiar principle to avoid tracking by the time when informations floud throught the system.
They all want real time video and active web pages. It is unfortunate.
You can have both.
Anonym communication and social media with posting pictures of your food. But with things like mixmasters, it's remains your choice which level of privacy you need.
P.S.: Maybe, I should ask on reddit or in a technical forum about it?
