> Once money is distributed, scams will appear pretending to be a worthy OSS project
That's not how it works. Rather, very nice people will insert themselves into already established projects and start siphoning the money to themselves, their friends, their businesses and so forth. You have a problem with that? Then you are toxic and probably several different "-ist", and should be removed from contributing.
This is very real, it even happens in corporate projects that you are the main contributor of.
