It is good that duckduckgo donate that money to free software or "open
source" as they like to call it. But there is an issue with duckduckgo and it
is that their javascript does not seem to be, at least, fully free as in
freedom and their non-js alternatives does not support all functionality like
image searching. It's interesting to point out that Startpage and Ixquick can
work without javascript perfectly.
I think that they should handle that issue first if they want to contribute.
In this post, one of the developers said that they are "opening" parts of ddg
progressively but with this answer they are not telling us if they going to
free their js:
