When other people rely on your hobby it can be hard to just walk away. There is pride, dedication and the feeling of providing value in FOSS. But if others make tremendous amounts of money based on your unpaid work, and show entitlement to its benefits and free support or development, it is hard not not feel a tiny bit entitled for compensation.
If other people are making money off of your hard work... stop rewarding them with free work.
But it's nauseatingly entitled to just expect people to pay a person for their hobby. Pick a different hobby if it upsets you? There are other things a person can do with their time.
