What about people who value helping others more than the money? and Disagree about the value of the "help" an `npm` package actually is? I like this idea but I can see there's room for disagreement.
Say there's a particularly problematic package... are you justified in hiring a bounty coder to replace it? How about a bounty hunter to eliminate its current maintainer? Is the action more moral if many people gang up to fund and direct the bounties' goals?
Telling people their "gifts to the world" shouldn't exist isn't likely to make you popular. The dumpster fire of NPM being a public hazard is hard to argue against too, so its a hard one.
