If you are willing to spend a decade marketing privacy features and bashing the establishment, yes. They are not Google-style "tech disrupters". One could say their success is as much a product of Edward Snowden's revelations and the subsequent societal shift towards tracking-as-a-liability as much as actual technology. Don't get me wrong, their UI gimmicks like !g are nothing to be scoffed at. UI has value, just ask Robinhood and Stripe. But DuckDuckGo is certainly not "hard tech".
You sure could. But DDG is a decade old company and its total lifetime searches amount to less than a week's worth of Google searches so it's likely your efforts will be in vain.
I feel like people tailor their lives around their children for the most part. During December, most people tend to just take their vacation to coincide with their children's.
