As writing this DuckDuckGo.com is the favored search in Firefox ESR on Pure OS. With this comes trust issue because of several reasons:
- Based in US; US laws give the US government the authority to compel a legitimate privacy-focused company into a data collector for state agencies. (surveillance programs, being prohibited from disclosing due to lawful data collection)
- Servers are hostet by Amazon in US. (data collection by PRISM)
- Started by Gabriel Weinberg (sold Names Database of the so called social network, including all the user data). DDG is privately held and also backed by various VC investors.
- Stores all search queries.
- Has not been audited.

At times i am also user of DDG cause usability is great. But putting it default for world-wide usage questionable. Examples for better alternatives are:
