Seemingly DuckDuckGo browser allows MS to track your IP address, especially when using Bing or LinkedIn.
It is a browser restriction but not their main search engine.

I actually use Vivaldi or Tor with DDG search with ad blocking (uBlock (Origin), Pi-hole (& Raspberry Pi)).
I guess I could use Opera VPN with DDG searching.

Reckon, I'll have to type alternate letters in separate browsers from now on.
