In a new official statement on the Directive (English translation), Kelber warns that Article 13 will inevitably lead to the use of automated filters, because there is no imaginable way for the organisations that run online services to examine everything their users post and determine whether each message, photo, video, or audio clip is a copyright violation.
Kelber goes on to warn that this will exacerbate the already dire problem of market concentration in the tech sector, and expose Europeans to particular risk of online surveillance and manipulation.
