No idea what your analogy about non conventional medicine is about. Feel free to explain.
just be visible to your home network’s ISP instead of your phone’s ISP.
Indeed, which is already what I mentioned, namely another group. It’s about the threat model namely if you trust one ISP more than another. I believe your understood that but chose not to acknowledge it and I’m not sure why but maybe it related to your analogy that I didn’t get.
Edit: if you and others are interested in the topic I recommend https://splintercon.net/ plenty of resources on the topic.
PS: FWIW I didn’t suggest VPN is the solution to all problems but they do alleviate some. The point is one must understand both how they work and their OWN threat model rather than an idealized one.
I believe it’s because they assume it’s not necessary because it was until now
… so I imagine there was no authentication because there was no practical threat beside few “fun” examples in CCC or DEF Con.
