There was a man named Richard Stallman who created the Four Freedoms of Software. F0 is the first freedom which is to run a program for any purpose. F1 is the freedom to study how the program works, and modify it how you see fit. The next one is F2, or the freedom to redistribute copies. The last freedom is to improve the program. The way that ties into crowdsourcing is that when multiple people are given the freedom to alter a program, the credibility of it tends to become stronger. Wikipedia is the primary example of crowdsourcing. This is where anybody can create an account and alter the information on a page they wish, and make sure that what is featured on the page is the most accurate representation of what the topic is. On the other hand, you can also add whatever info you want, no matter how outrageous it is. At the end of the day, crowdsourcing has the right intentions, but without the secure regulation from the government, people can add whatever they wish.
