According to Tech-On! magazine, Fukuda Tadashi the president of Kadokawa Digix (the publisher of "The Melancholy of Haruhi Suzumiya", "Lucky ☆ Star" etc.) said "It is quite sad to see that anime vids are deleted due to the copyright infringement. We can use Youtube and other video sharing service to advertise our titles outside Japan." He continued "Anime fans who wanna see anime in higher resolution will buy DVDs. People watch anime on Youtube because they have missed the TV broadcasting or wanna check it just on trial. Currently we give up the chance of selling not only the DVD but the illustrations or other character products. Those fans take their time to upload and advertise our anime titles. If we keep on claiming copyright infringements and neglecting their activities, we eventually lose anime fans."
