In my case, even from a self interested point of view this makes sense: this only applies to improvements and bug fixes on some Clojure libraries, but: If I contribute back to a library I use, I can raise the probability that other people use it and contribute to it, thus ensuring that my dependencies keep fresh; and by sharing work I’d do nonetheless, I do not lose anything. On the other hand if I keep my changes to myself, then I do not gain anything, but I contribute to the withering of the environment Im building dependencies with.
