There's a big difference, of course, between INTENTIONALLY pointing
your computers at DNS servers that do this kind of thing, and having
it done for you without your knowledge and/or consent.

As Steven Bellovin pointed out, most OpenDNS users will not choose it:
it will be choosen for them by their corporate IT department or by
their Internet access provider.

Our preference system is designed around CIDR and the most specific prefix will win a lookup meaning a /32 settings are preferred over that of a /24.

A corporate network can have a policy changing that (aka, you are fired), but an ISP can't. The policies of IT departments and ISPs are not remotely comparable. This is a deliberate design choice.

As usual, ymmv.
