Are you kidding me? If that extremely-slick dashboard (I hadn't seen it before) is representative of the quality of their UI for all their products (I actually doubt it is), as an enterprise/government company I am shocked they have not yet annihilated their competition. If it is representative, we now know why they have to spend money on lobbying - the only reason their competitors are alive is because of entrenched influence.
What's hilarious is you've broken down individual components of Palantir's offering and made the case that each individual component can be replaced by open-source or by a competitor. But that's literally missing the forest for the trees. It's the whole integrated package that matters. Nobody (or very few) is doing the whole package as well as they are.
