It's unclear to me what "internet platforms that organise and promote large amounts of ... works uploaded by their users" really means. It presumably applies to Facebook. It presumably doesn't apply to e-mail. But if I had a social networking service that had no advertising and was only accessible to its paying users, would the law apply to it? What if postings were encrypted and could only be read by users that had requested access to them? Would the company running the service be expected to either backdoor the encryption or create bogus accounts and request access from those bogus accounts in order to monitor postings that might contain infringing content?
