University of Kansas issued a report which says that the network file does not hinder the music, film and typographic industry. The report says that, despite assurances from such organizations as the RIAA, the weaker the copyright would benefit both society and the authors themselves. Researchers recognize that piracy can be detrimental in some business models, but emphasize the existence of successful business models, where piracy has charitable impact on the industry. Network file does not reduce the incentive for musicians and artists creating new works, on the contrary, they may lead to even greater number of new works. This is a serious argument against strict copyright.

The United States Constitution specifies that copyright supports the progress of science and the arts through the provision of protection of exclusive rights to work and the opening of their authors. Thus, she postulates that the indicator for copyright should serve the progress of science and art in the era of file-networks. Even if due to file-sharing reduces the profitability of the direct product of the individual, this is not an indication that the industry as a whole suffered substantial damage. Firstly, the weakening of copyright reduces the price of music, films and books, and consequently increases the willingness of consumers to pay for the work, and consequently increasing sales. If the author receives income from this, the incentive to create new works, not only did not fall, but may even increase. Further, if the individual music tracks are actually free, the prices for the concerts can be increased, as will be more willing to go to a concert, and the total income of musicians will not be reduced. Similarly, the authors of the books may be paid to hold meetings with readers in different cities, which are possible only if many people are familiar with the books of the author.

Economists say that it is necessary to carefully assess the extent to which revenues from complementary products offset the decline in revenue due to Internet piracy. Furthermore, according to the authors of the study, piracy increases in other areas, in particular, it leads to more rapid development of Internet and the growth of consumer electronics purchases, i.e., televisions, HTPC, etc., necessary for viewing and listening to the files. "The copyright exists to encourage innovation and creation of new works that is to promote social welfare" ─ write the scientists. ─ "That is the question of whether new technologies to undermine the incentives for the creation and dissemination of works." Yes, given the data showing a significant increase in music and film industry, it is difficult to accept that the network files somehow reduce the incentive to create new works.
