The entitlement and audacity of people who consume open source blows me away. I've maintained a project for 12 years and recently someone wanted me to help them implement the software in their system. I politely told them that since this wasn't a bug, they would need to purchase a support package. They then accused me of trying to "sell open source software" and closed the issue. People are unbelievable. Fuck me for trying to make a living providing you personal development time, using my software that I've supported for free for over a decade.
