  • Just a reminder that WhatsApp is also owned by Facebook
    Meaning, you can go to public instances like searx.me,. Here's the documentation on how to start it up. But , you dont have to trust Searx that they are good people nor do you have to trust their data habits like DDG. Source: over 4 years ago
  • Instead of lashing out at duckduckgo for doing what they think is best, ask the deeper question of why weโ€™re all still using centralized services and being disappointed when they behave in a predictably centralized way.
    Consider a future where something like https://searx.me/ is as ubiquitous as Tor. Source: over 4 years ago
  • DDG, once a hero has now fallen.
    For those looking for a replacement for Duckduckgo; I would highly recommend using Searx.

The link I sent is the primary instance, but here is a link with dozens more, and my own private instance. Source: over 4 years ago
  • DuckDuckGo is out. I guess I'll try Brave Search.
    The most based solution: Https://searx.me. Source: over 4 years ago
