Probably anyone who's interested will know, but I think that it's worth noting that Ghostery ( https://www.ghostery.com ) is not tracking software; it is anti -tracking software, meant to track ads' tracking behaviour. (Thus this purchase is, presumably, a good thing.) I think that calling it an "ad-tracker tool" risks misleading the casual reader.
The thing always got mentioned whenever Ghostery is brought up is that they were owned by an advertising company that sold user data. I wonder how Cliqz plans to make this a profitable venture (besides being another Mozilla charity case)?
Whether or not it's a convincing case, the article does address that:
> Cliqz has previously discussed its plans to monetize this pro-privacy approach and usage of its free, anti-tracking browser and search products via a companion Cliqz Offers app — that will be designed to broadcast all offers to all users so Cliqz does not need to track individuals’ browsing habits to power ad targeting. Rather tracking of browsing habits occurs locally, on a user’s device, allowing for the tech to display pertinent offers to users without Cliqz itself needing to be party to its users’ browsing behavior.
