Not free-riding
Wikipedia is one of the world's largest and most popular public goods. Students around the world are able to access archives of information for homework, general knowledge, and random wasting of time on the internet. However, Wikipedia is not free to operate, as it requires money to pay its staff and maintain its servers. Free riding is one of the biggest issues for Wikipedia, as millions of people use it daily without incurring any of the costs. Assuming Wikipedia thinks they have too many free riders, which solution would NOT reduce, or offset, the free rider problem?
Wikipedia creates a duplicate website, Wekepedia, with the same content as Wikipedia, but costs $25$25 a year. Wikipedia would remain free to the public.
