Title seems wrong, it sounds like Dragonfly is still undergoing active development, just with reduced data access (no more access to 265.com search data) but the article references ongoing development, even though some developers were removed. That doesn't sound like it's actually ended. And the title's quote of "Effectively Ended" seems only to be quoting itself, there's no one in the article the said those words.

Pichai's words to congress could easily be read to mean "we don't have a release date at this time" not that it wasn't still an active project.
