Perhaps they mean choosing a default search engine in Chrome is not as straightforward as Firefox.

Because someone has to be arsed to write it?
I suspect that part of it is a confluence of events: it's not exactly easy to change the search to DDG, most Chrome users don't bother to change it, and no one who is capable really wants to write an extension for Chrome to make it easier.
Which is, to my mind, a far simpler explanation than a conspiracy against DDG (in that one area).
