Internet is already federated, its just called peering instead?

I think idea is that the app would already be there, for a journalist, having Signal is probably a given.

A journalist or political figure can install a $5 VPN.

And even in their own example attack against the Discord CTO, their location got them down to 90% of the US. I could have guessed that without the attack.

Do any of the good VPN providers leak DNS? Most VPNs claim to allow evading geolocation, if they leaked DNS that wouldnt be true?

Doesn’t even guarantee physical location, only the location of their VPN endpoint.

Quite overblown, this tracks people to the nearest cloudflare region. Not really de-anonymising, especially as you have to already know their contact details.
