Whether Cliqz would become a bully like Google if successful or not, I believe it's impossible to answer.

But at least, we know, that the data we collect from our users to build the search engine is totally anonymous and is used only to build search and the browser.

So, in the case that Cliqz would turn evil, I would stop using it, knowing for a fact that there are no sessions about me on their data, none.

Someone on the thread mentioned fiduciary duties, true that companies must maximize profit, but that does not mean becoming a gear on global surveillance conglomerate.
