Lawmakers have approved a sweeping overhaul of copyright rules, dealing a blow to major tech companies that argued the changes will be costly and limit free expression. The European Parliament voted Tuesday to approve fiercely contested changes that make platforms such as YouTube responsible for copyright infringements committed by their users. Sites like Google News could also be required to pay publishers for using snippets of their content. The proposal was opposed by tech companies, which warned they would need to build expensive content filters and stop linking to publications. Internet activists argued that the changes would lead to censorship. On the other side of the two-year battle were record labels, artists and media companies. They said reforms were needed to update copyright protections for the internet age and to ensure they're fairly paid for content.
