After watching Gunderson’s presentation, I did develop a deeper understanding oncopyleft and copyrights. I used to ignore the importance of these two definitions and thought that these things was far away from me. But Gunderson’s delivery helped me a lot in discovering the copyright issues in daily life and changed my point of view. After this, I will respect the author’s copyright more and resolutely resist piracy, which is what the creator deserves. In my writing class, the teacher always ask us to cite the sources, I used to think that is a waste of time to do so. However, from Gunderson’s presentation, I understand that citing the sources is not only proof that I am not plagiarized, but also a sense of copyright and respect for the author.
