From what I recall, talking to one of the Tor founders about this, Tor was created with overseas US military personnel in mind. E.g. A soldier’s location could be compromised through foreign ISPs if they accessed sites like .mil domains directly. Tor was a way of preventing this problem. There were other use cases but this one stood out for me and it was one of the initial ones considered.
Pretty on point with what I'm saying. I remember when Tor first launched and it was definitely framed at the time as for human rights. I absolutely believed all of that for years.
You yourself spoke with the founder about this?
The development of onion routing funded by the NRL had a bunch of use cases including the one I mentioned. By the time Tor (The Onion Router) launched, and definitely by the time the Tor Project came along, more general use cases and human rights were a significant part of it.
I did have the chance to attend a talk by one of the cofounders and have a conversation with him afterwards. This was at a math conference a little over a decade ago.
