I am one of those companies running a recursive DNS service, DNSFilter.com
We are not advertising driven. OpenDNS cut the ads a few years ago.
We do not run open resolvers, we just have paying customers who wish to use our service.
The DNS extensions you are referring to are the EDNS0 Client Subnet extension. It is in wide use by authoritative servers for major CDNs and is supported by a number of recursive DNS providers. See the spec here: https://tools.ietf.org/html/draft-ietf-dnsop-edns-client-sub... Section 11 addresses your concerns about IP addresses being shared: It is encouraged to provide only as much granularity as is necessary based on network architecture. At no time is there a reason to share the last octect of an address (since Internet BGP routing is limited to a /24)
We do not run an authoritative DNS service, yet are working to improve encrypted communications... in coordination with industry authoritative partners. Very early stages, but we are driven to protect our customers and the Internet at large. Every time I hear someone misunderstanding what DNSSEC is, and why they think they want it, I'm encouraged to work on solutions such as dnscrypt or DNS over TLS: https://tools.ietf.org/html/rfc7858
