Lets not forget that Gabereial Weinburg is a two faced ghoul or wolf in sheep clothing. He has literally said he does not believe people need privacy yet that supposedly is the duckduckgo's main selling point. He has made all kinds of tracking deals with other companies so duckduckgo "is not tracking you" just their partners are.
Most of the controversial stuff he has done is being whitewashed from the internet and is now hard to find.
