RE: Greatly improve your security using NextDNS

It's a great product, but it's a centralized vendor. I'm willing to pay for a subscription for the service of curating whitelists/blacklists, signature data and IP/domain reputation databases. BUT I like to pay anonymously without need for an account and to avoid centralized single points of failure. All security related software (and hardware, too) should be opensource with the ability to fully self-host without depending on a vendor, its services and availability.
Pi-hole for example can be configured to fully run local on a pi, being a fully recursive resolver without any external dependency.
