That's never been interpreted to require, for example, that the USGS needs a warrant from a court to make a map. Similarly, Palantir's collection of data isn't considered to be owned by those who it documents. I may despise Palantir, or think there should be other reforms to how data "ownership" works, and I may think that private companies are creating a giant Constitution-circumventing loophole, but it's very disengenuous to suggest that our history would make any government purchasing or licensing of something from a private business subject to a warrant.
