"Since Article 13 places platforms in the direct line of fire, it will force services like YouTube and Twitch to impose strict filters and limitations on European users. Twitch streamers who live in Europe will be severely limited in what they can stream. According to the letter from Shear, the constraints Article 13 places on streamers means “content would be much more difficult to publish, including commentary, criticism, fan works, and parodies.”
"Right now, most video services scan for copyright infringement after a stream has ended or a video has been uploaded. With Article 13, services will have to scan for infringement live during streams or have content creators prove they own their content before they even turn on their webcam. Streamers living outside of Europe will have to prove they own the rights to publish if they don’t want their channel blocked in European countries."
- Streaming games is still allowed (AFAIK) but you won't be able to stream copyrighted music, so..
