People are inherently selfish. Everyone is looking to better their own self-interests, seek validation, and seek attention in life. A community - any community - is made entirely of these people.
An effective leader is one who can play to the strength of this fact rather than fighting it. You have thousands of people willing to spend their time for you. How can you make their interests align with your own? How can you convince them that your self-interest is their self-interest?
Funny, but I don't think calling people entitled is the answer to this.
