some free programs shave. some bill the members when/if they use the member services. some free programs bill after 12 or 24 hours.

as far as how free programs can treat their members poorly, they can cover them with popups if they don't join, and drown them in popups if they DO join. they can install dialers that the people can't get rid of, or they can install spyware or toolbars or all sorts of things. they can still not actually provide the content promised in the tour.

you know what i REALLY don't understand? when one builds a tour, and it sells, one is in a very good position to know exactly what the members want - they want what is on the tour. why not just give it to them and enjoy the rebills?
