Your analogy actually shows why “open” is appropriate in this context. It’s true, you don’t have to cut the grass or fill a pothole in an open park or an open road. Similarly, you don’t have to fix any bugs in an open source software either. But if you do, you cannot stop others from using the fix. In your analogy, if you do fix a pothole, you cannot prevent other road users from using the patched portion of the road.
