Why was it so easy to weaponize copyright against PewDiePie?

Live streams or prerecorded “Let’s Play” videos are hugely popular and often lucrative, but they rest on a shaky legal foundation. Almost by definition, gameplay videos are full of game developers’ copyright-protected art. So without a studio’s permission, these videos are only legal if they count as fair use — a DMCA exception that protects criticism, parody, and other creative repurposing of a copyrighted work. Fair use is a broad standard decided on a case-by-case basis, but artists and entertainers in some fields can look at past legal decisions for a sense of what’s acceptable. For Let’s Play videos, these cases are almost nonexistent. – Adi Robertson, The Verge http://ift.tt/2wUJ3j6
