The creator of the World Wide Web, Sir Tim Berners-Lee, has warned of three big Internet dangers, and of how people are misusing the Internet. The first danger is that companies and websites are creating fake news just to make money, or to change people's political opinions. He said fake news "spreads like wildfire". The second danger is political advertising. Adverts are used in "unethical ways" to stop voters from voting or to send them to fake news. His final worry is the misuse of personal data. He said some governments kill people because of the websites they visit.

Berners-Lee invented the web in 1989. He said that it had "lived up to [his] vision". He said: "I imagined the web as an open platform that would allow everyone, everywhere to share information, access opportunities and collaborate across geographic and cultural boundaries." He said there were now difficult problems that have no simple answers. He wants to put, "a fair level of data control back in the hands of people". He also wants to stop governments from misusing data, which he said affects free speech. And he wants to fight against fake news. He called on all Internet users to help.
