To help those who might not be familiar with these last three bullets:


VPN0 is something Brave is working on; overview is here: 
https://brave.com/vpn0-a-privacy-preserving-distributed-virtual-private-network/

FPN is the "Firefox Private Network", which is basically two different 
offerings. One is an in-browser VPN, and the other is a traditional 
whole-device VPN. I'm only passingly familiar with the technical 
details, but my understanding is that the VPN endpoint is run by 
Cloudflare, and that egress from their network is selected based on 
proximity to the destination site, making correlation of IP addresses 
more difficult than a typical VPN. There's a bit more description at 
https://fpn.firefox.com/

Willful IP Blindness is a concept that Brad Lassey (Google) has been 
working on recently, and is summarized at 
https://github.com/bslassey/ip-blindness/blob/master/README.md
