If there is a commonly used open source library without hackable bugs, you won't even hear about the author who committed his/her own time to build reliable software.
If someone finds a bug, then she will get some prize, and will be invited to a conference. And the library author will be publicly bashed as an idiot.
Sometimes open source people don't even get mentions.
I was working on a patch for a huge open source project once. I spent hours on that. Two other people helped me, they also spent some significant time on that. And we managed to implement this. Who was mentioned in the release changelog? The person who committed that. Then I stopped spending my precious time on such things like giving someone the credits for my work. I love programming, I work on my own projects instead.
And all that makes me sad.
