Acá hay una síntesis imparcial. Bueno, es parcial, pero no fuerza el punto de vista de Mozilla:

>So, mozilla now decided that tracking all user activity and sending that data to a third party called “Cliqz”, based in Munich, Germany, majority owned by Burda media, a “news” and print (read: mostly tabloid) media group (Bunte, Focus, Chip, Freundin) is a good idea…
>I can only shake my head. Clearly Firefox is the “privacy browser” as they claim!!1!
>The dumb stuff they pulled in the past just pales in light of this.
>Initially they will “test” this “feature” in Germany with 1% of the user base there, they say. It doesn’t sound like it’s exactly opt-in, but opt-out, so make sure your data isn’t siphoned off next time you install/update Firefox.
