A situation that appears more and more, though, is that "with great power comes great responsibility." When using Free Software, you might only have yourself to rely on to maintain the software you use.
Don't get me wrong, most maintainers will go through great lengths to help their users, but that's from being kind and decent human beings, not from being contractually required to.
When using Free Software, it's also "free as in puppy": no upfront cost, but maintainance is on you.
