Greyball[0] is an interesting solution to a usually intractable problem while freebooting, how to prevent avoidable contact with interested parties, to the degree of identifying and tracking said parties. I’m surprised In-Q-Tel never made an investment, as these kinds of dual-use products and services are in their wheelhouse.
