It is unclear to me what you are saying here. It is well-known fact (amongst the intelligence community) that our software has been used to save tens of thousands of lifes, prevent hundreds (thousands?) of terrorist attacks, saved billions of dollar in fraud etc. In terms of most of the kind of projects governments do in an attempt to prevent {crime,fraud,terrorism,...}, on a scale for how much bang you get for your buck (where 'buck' might be how much data collection you have to do), I think you won't find many other alternatives that compare favourably. (But then, I might be biased, of course.) In fact, as I described in many agencies the situation actually drastically improves once they start using palantir software, since they already had all the data all along, but weren't properly using it as the law intends them to.
Everyone knows the various forms of law enforcement perform some measure of (and have to, to do their job) surveillance. That ranges from e.g. ALPR cameras to patrolling the streets of some city. Most people agree that this is a perfectly acceptable thing. Do you think instead the police should be abolished? Or stripped of their investigative or enforcing power? I don't think most people would actually enjoy living in whatever society would result from this.
Of course the exact boundaries of what is acceptable and what is not should be fiercely debated.
