It's really not that hard. The idea is that the people using the software are a community, and as such should be working together to make the software better. If you're just using the software, and not contributing back fixes, or offering financial support, then you're just taking and not giving back. Hence, the freeloader. Legally, the licenses do allow for that. Ethically, though, it's a problem, and makes you a bad person.
