“public good” is a highly variable term, though. While one person might argue that (example only) Palantir is the grossest public avil imaginable, another person could argue that they are a public good, on the basis of helping law enforcement.

How do you derive a legally acceptable definition of public good in investment? An evil person could invest just as much as a supposedly good person, but with the intent of making money, but otherwise be amoral about everything else related to the investment.
