>Someone in ICE uses Microsoft Excel to maintain a list of people who they believe should be send to an internment camp. Therefore Microsoft is an accessory to that?
Utterly disingenuous. Surveillance software is primarily sold to governments to spy on individuals. It doesn't exist for any reason except for the powerful to oppress the weak.
>Where do you draw the line?
"I just kept turning the heat up and the frog seemed perfectly fine. The fact that it's cooked now can't have anything to do with my actions." I don't have to propose a generalized demarcation criterion to say whether a particular example is on either side of the line.
Since when has Palantir sold surveillance software? They sell data integration software and they don't store, transfer or share customer's data.
If surveillance software is your issue, then companies like Cisco or Huawei are provide the hardware and software. But like most technology, there is always potential to use it for things we disagree with politically or personally.
