This is a victory in a long fight, not just against blanket police surveillance, but also against a culture in which private, for-profit companies build special tools to allow law enforcement to more easily access companies’ users and their data—all of which ultimately undermine their customers’ trust.
Yup, a simple Wireguard setup would work fine.
I also like Tailscale, but unless you’re running it with Headscale, then technically they hold the keys.
