> I'm dropping your software without a second thought.

Ha, it sounds like more work to replace a free piece of software with something else than to use your own patched version. Especially if you have to replace it with something inferior or proprietary. If there are better-maintained alternatives, why did you adopt it in the first place?

Pull requests take work to review and test. You shouldn't take that for granted and assume everything will be merged for free.

If you manage to review and test fixes faster than the original, or if you're willing to add features and maintain the code yourself, go and promote your fork!
