I guess you're not an opensource developer. Let me put it in terms that you understand:
Let's say you're a pizza delivery dude. You have to be out every day, delivering people to rude customers, no matter the weather. It's hot and your balls are sweating off, if cold and your fingers are freezing, there torrential rain and you get soaked for every delivery, but bossman don't care - you have to do it!
To relax, you have a hobby as a wood worker. It's your passion! You make small things to make life a little easier or things that look cool to you.
One day, you buy a cupboard that's been all the rage. Every store out there has it and it's flying off the shelves. But after a few months there's something annoying about the way it works. Not a problem for you, the handyman, the woodworker. It takes a few weeks, but you've designed, built, and tested a few solutions to arrive at something that works. It's not beautiful, it's not trendy, sexy or anything, it just works.
Thinking to yourself "hey somebody else might find this useful", you put the designs online. To your delight, there are a few people using it. Very few "thank you"s, but that's fine, at least it helped somebody.
Then one day, some dude writes a comment about your solution titled "Build something beautiful or GTFO".
Tell me, how would that make you, as the hobby wood worker feel?
How do you know somebody's American without meeting them first?
You hear them.
