If we have location-based results it means that they shares (let's say) the gussed city name with Microsoft. Saying *we throw away both the guessed location and the IP address* is bullshit. They share it with Microsoft, and Microsoft keeps it.
I'm not sure I understand or maybe I'm missing something, sharing the guessed city is not "technically" sharing your IP address? (I understand that it's still sharing more info than what you thought)
Let's say the steps are:
1. You type in "exhibition" to ddg
2. DDG sends "exhibition in <guessed city>" to Bing using its own random datacenter IP address
3. Sends you back results
Did it now "share your IP address with Microsoft"?
Then it says we throw away the IP and gussed city name, which is correct. But they have shared the city name with Microsoft.
I will update the title to fit the described problem.
Your initial accusation here and follow-up are unwarranted.
