Some people are takers and don't give back
When I look at publicly provided services that are free is that they are underfunded and exploited. As people take advantage of what can be taken for free. Free and fair things benefits everyone as it raises the tide of all boats. But some people take advantage.
Whats a useful solution to the freeloader problem?
One can look at open source for an example. Large corporations and software engineers for large corporations take open source software for free that has invested in it thousands of open source developer hours but companies don't give back but create millions in profits from it.
