DMCA needs to be changed to WIPO
DMCA is in the long and short run a USA policy that does not cover or attempt to handle a International Audiance. As Twitch needs to change to WIPO (World Intellectual Property Orginization) standards like YouTube, Netflix and other companies. Mind you the WIPO does respect the DMCA but unlike that policy was founded and created with a international audience in mind. Numerous counties, and the US is inculded, do recognize the WIPO as being fully legal and binding for international copyright issues.
A good example of this is Viacom vs YouTube. Viacom used DMCA against YouTube in a lawsuit over showing it's music and content on there streaming service. However this backfired as YouTube due to having international users, was in fact respecting the DMCA as per WIPO guidelines. So the courts ruled in favor of YouTube. This was a court case held in 2007, then challenged with increasing evidence against YouTube in 2010 and 2012. The results always being the same, in YouTubes favor.
As such I believe that it might be time for Twitch to do the same as those other services and recognize that it has a users from more then the USA. Mind you this is just my thoughts but I think it is likely time and a idea on how to improve the whole DMCA policy in a way that will help Twitch grow and support our streamers that are bothred by the approach of it's use at the same time.
