Not sure how you figure that.
The fact that it's Open Source or Closed Source doesn't mean that the author(s) will keep it maintained or not.
In fact because it's Open Source it protects you from being stuck with an abandoned piece of software. Someone, you for example, can pick up the source and fork it or supply patches for bugs or new features.
In either case there is always the expectation of users that the source keeps being maintained.
