one on VPN usage, two on decoy routing, and one on rendezvous using
cryptocurrency.

Abandonment of VPNs as a Privacy-Enhancing Technology

    Questions to ask and goals to have:

    What aspects of the paper are questionable?

    Are there immediate actions we can take based on this work?

    Are there long-term actions we can take based on this work?

    Is there future work that we want to call out, in hopes that others
will pick it up?
