That's not quite right. The advantage is that you (and others) are ALLOWED to do what you want with it (within license limits), but there's no guarantee that you have the resources to make use of that right. Even maintaining the status quo might require more resources than you have as the world evolves and bit rot sets in. It is nice, though, that open source leaves open the possibility that some other party can pick up the ball if the original developers drop it and you can't do it yourself.
