What's a valid "threat model"?
If you start your own data center, lay your own fiber, and peer with ISPs and hosts, well, everyone knows who you are again.
There’s no escaping trust issues 100%. The idea of a threat model is all about the trade offs, what things you will decide to trust or how you will defend yourself in depth.
Hint: You're probably not trying to thwart the most sophisticated branches of a nation state.
