"A well-recognized strength of the fair use doctrine is the considerable flexibility it provides in balancing the interests of copyright owners in controlling exploitations of their works and the interests of subsequent authors in drawing from earlier works when expressing themselves, as well as the interests of the public in having access to new works and making reasonable uses of them". (Source: Pamela Samuelson. Unbundling Fair Uses, 77 Fordham L. Rev. 2537 (2008)
"Fair use does not “free ride” on original copyright as it neither reduces the economic value of the work nor does it substitute the original. Thus, it does not affect the return on the work and therefore, the incentive. Rather, it lowers the social cost as it allows others to use the work".
