As The Verge's James Vincent reported, "Article 11 lets publishers charge platforms like Google News when they display snippets of news stories, while Article 13 (renamed Article 17 in the most recent draft of the legislation) gives sites like YouTube new duties to stop users from uploading copyrighted content".
Julia Reda, an MEP from Germany's Pirate Party, described the passing of the law marked "a dark day for internet freedom".
This directive - when passed into United Kingdom law - will give directors not only the right to fair and proportionate remuneration but it also equips us with the legal means to defend and protect this right, wherever and by whoever their work is used.
However, critics say that the law is vague and may actually end up restricting online content and thusly free speech.
There were similar protests in Austria, Poland and Portugal, while major Polish newspapers on Monday printed blank front pages in an appeal that MEPs adopt the reform.
They also note that given the cost of deploying such technology, the law may have the opposite effect to its intent-accidentally solidifying the dominance of USA tech giants over online spaces.
At the heart of heated debate were Articles 11 and 13.
Under the reform, European law for the first time would hold platforms legally responsible for enforcing copyright, requiring them to check everything that their users post to prevent infringement. But if platforms are to police the content, it's possible that they'll simply ban certain types of content altogether using so-called upload filters, ultimately stifling creativity and freedom of expression.
The legislation was criticised by the public and even executives at a number of companies. YouTube CEO Susan Wojcicki and global head of music Lyor Cohen both spoke about how Article 13 could negatively affect creators on YouTube.
The second article advocated the creation of a "neighbouring right" to copyright for news media. Social sites such as Facebook are likely to bear the brunt of the new law, and there are widespread fears that it could fundamentally change the face of the internet. Once published on the Official Journal of the EU, Member States will have 24 months to bring the new rules onto their national books.
But opponents have called it a "link tax" that will stifle discourse on the internet and pay only big media companies, with no real benefits for journalists or news gatherers.
