We have a bunch of socially minded people providing free value in the form of open source that enjoy the gift they are giving to others. When they become aware that their charity disproportionately benefits selfish people who have opposite inclinations - who employ people to search for exploits, without fixing them, to suck up as much wealth as possible - I'm not surprised they would want to take a step back and ask for a share of that.

And that's totally fine under the same market mechanics you're recommending. If you want maintainers to stop complaining and filing potential petitions asking for funding via taxes etc, just pay them.
