What you propose is sensible and funneling more of the wealth that corporations derive from using OSS projects back to the development of these projects is certainly a desirable thing. But there are other problems discussed in the post and I'm afraid some of them cannot be solved with money alone. Suppose you are overwhelmed with a thousand meaningless pull requests. Whom you are going to ask for money? Suppose you are called a douchebag for rejecting an ill-thought out pull request. How is money going to mitigate the vitriol? Suppose you are called a douchebag for asking money to fix bugs. Same thing. Attitudes need to change too. There needs to be growing recognition of the respective contributions of users, developers and maintainers of OSS projects and their value.
