This just doesn't make sense when the government is the customer. If you have a problem with what Palantir does, then your real problem is with the government because that's who is actually putting the tool to use. Why would you go after the vendor instead of the government who will just keep doing the same thing if you go after Palantir?
given the current administration, i'm not holding my breath.
