> creating an open source project is a contract with the community, and part of that contract is to assist members of this community

I disagree. Creating an open source project is a gift to the community.

Expecting further time and attention from somebody who gave you a gift, out of a sense of entitlement from having received the gift, is just being rude.

Pay for my time and I'll help you with your issues. Demand my time because you're somehow my "community" and I'll just re-explain the above.
