I knew of the Site Finder incident, but I am not very familiar with the details. That said, isn't the big difference with OpenDNS that it is opt-in? You don't have to use it if you don't like the advertising component, but they are providing much more than redirects of unregistered domains. They also correct misspellings, block phishing sites, and any other category of domains you want to filter out. Especially in a corporate setting, it seems like they can provide quite a bit of convenience.
