What's wrong with Chromium btw?
It's made by Google.
What else do you need to know?
What's the point in using a distro that defaults to DuckDuckGo, on the basis
that Google cannot be trusted, if you then install Google's browser? It might
not have closed source code in it, though I doubt very much if anyone from
the libre software brigade has checked every single line, but we know that
Google harvest data and profit from it, without any benefit to anyone else
(they probably don't pay any tax on that profit either, they certainly don't
pay much tax in the EU/US/UK).
