But federal copyright law too easily allows Internet giants like Google and Facebook to duck accountability for costly copyright violations when users upload massive amounts of infringing content on their sites. With a new Congress now in place, it's time for an overhaul of the "notice-and-takedown" system for removing infringing content from Internet websites. A draft bill released on Dec. 22 by Senate IP Subcommittee then-Chairman Thom Tillis, called the "Digital Copyright Act of 2021," offers a promising route to overhaul the old system. The 117th Congress should refine and advance the Tillis bill or similar legislation to make user-upload sites more proactive in stopping infringements.
