Well this is false, and misleading. The connection to Sidefinder is a red herring -- sitefinder was applied Internet-wide, OpenDNS was a choice. Saying OpenDNS redirected www.google.com isn't accurate either. There was a URL that was redirected for a portion of users for a very short period of time because Google installed a hijacked version of the Google toolbar, and once we did this, they reverted their erroneous behavior and we reverted ours and we wrote about it extensively (https://umbrella.cisco.com/blog/2007/05/22/google-turns-the-...).
Geoff knows better, but is being lazy or sloppy while trying to provide a historical record. A shame, because it's a worthwhile topic to go over.
The real conclusion he fails to make is that between Android, Chrome, and Google Search, there is a total monopoly on navigation for the vast majority of the Internet. That's distressing, and until there is a major platform shift, it's hard to see that changing.
