> How is Palantir a loophole?
The big legal loophole is that the government needs a particularized warrant (per the 4th Amendment) to ask for any user data, but if the government buys commercial data, well, there's no warrant needed.
I would also submit that it's possible that sending everything through a giant computer-magic-bullshit-mixer allows you to discriminate on the basis of race while claiming plausible deniability, but SCOTUS has already constructively repealed the 14th Amendment between blessing Kavanaugh stops and the Roberts Court steadily repealing the Voting Rights Act, Bivens claims, etc.

See also: Parallel Construction (i.e. evidence tampering) and most of the times a "drug-sniffing" dog is called to "test" something the police already want to search.

Right; but as far as I know Palantir don't sell commercial data. That's my beef with this whole Palantir conspiracy theory. I am far from pro-Palantir but it really feels like they're working as a shield for the pitchforks in this case.
Which has what, exactly, to do with Palantir?
On a somewhat related note, it always bothers me that the discussion is about whether it’s appropriate for the government to buy this sort of data as opposed to whether it is appropriate for anyone to sell, or for that matter collect, that data.
I would prefer if neither the government nor any data brokers or advertisers had this data.
