My name is John Lloyd, head of European campaigns at Mozilla, and today we're here to do something special for The Guardian. When The Guardian noticed that old articles of theirs were being posted as new news to push extremist viewpoints online, they added the date so that people knew instantly that what they were seeing was an old story. This is a small but very important step in fighting misinformation online. So we're here today to deliver a giant thank you card signed by the Mozilla Foundation and nearly 27,000 other Mozilla supporters. It's just our small way of saying thanks to The Guardian for taking leadership in fighting against misinformation online, and if other publishers take the same step, we'll be able to go a long way in fighting disinformation worldwide. So on behalf of Mozilla and nearly 27,000 Mozilla supporters, we just want to say thank you so much for stepping up to tackle misinformation online. Whoa! Wow... Whoa! Thanks so much, it's a really fantastic thing to be able to get a card with so many signatures that help us understand that what we've done is something that other people value too- especially in an age when, with social platforms, people need context around journalism more than ever. So thanks ever so much and thanks to everyone who signed it.
