The European Parliament passed a controversial new directive Tuesday that increased online publishing platforms’ accountability for copyrighted material posted on their sites without owner consent.

Many U.S.-based tech companies, including Google, Reddit and Twitter, have spoken out against the directive, especially Articles 11 and 13, which would impact online publishers and require platforms to filter out or block copyrighted content, potentially including remixed material. Critics said the directive could hamper online creativity, lead to over-censorship and force companies to drastically change parts of their sites in Europe.
