I just gave you what took me about 60 seconds to web search.

You could maybe do your own actual research, you know be active, and find way way way more information, fairly easily, than what I linked here, to just illustrate the point that you aren't paying attention.

Also, to your points:

1] It does, actually. If you provide your services to a cyber warfare outfit, you are now involved with and facilitating cyberwarfare.

2] You apparently don't know what a kill chain is, look it up. Palantir has directly been doing target identification, tracking, and assignment of lethal munitions toward Palestinians, and others. That's not cyberwarfare, its just warfare, the comms network behind coordinating it. It has to be harderned against cyberwarfare, via encryption and other kinds of security measures.

3] This is either a non-sequitir or you don't anything about cryptography. Yes, yes indeed, massive data analysis capabilities are used in cryptography, to decrypt things. You look for patterns, in data, and then try to reverse engineer a semantic structure. This is a kind of data analysis... called cryptographic analysis.

4] Right, I'm sure that Palantir doesn't keep their own copy of the data they recieve, or the analytic results that the derive from it.

... Have you worked in tech much? I'm guessing no. Look up 'data broker' as well.
