"Cliqz sounds too much like an off-brand, gutter ad seller to ever have credibility, and I say that as someone who was fairly impressed with their tech."
That's because they were. The parent company was in adtech and they even had another subsidiary that was hawking browser toolbars.
Frankly though, the Brave brand has no better reputation with me however, so it still means seeing whatever promise the tech might've had consigned to the same headspace as the rest of the scamweb.
