This seems to be solidly on the side of justice.
Should they have blocked Google and Bing after the invasion of Iraq?
Bing didn't exist in 2003 (launched in 2009), and I don't think that Firefox ("Firebird" at the time) had a search bar with search engines.
That got me curious, so I fired up some old versions of Mozilla Phoenix and checked that out. Turns out already Mozilla Phoenix 0.2 (https://ftp.mozilla.org/pub/phoenix/releases/0.2/), released on October 1, 2002, which was the version which originally introduced the search bar, offered the ability to select different search providers.
Hey, that's interesting. Thanks for looking into it!
Bombing civilians in the middle east didn't stop in 2009.
What you're looking for is not "free", it is still free software even if they change the default search engines that come pre-configured in their software. You are looking for software aligned with your politics (which is fine!)
I may need to seek a more "free" alternative
