Sir Tim Berners-Lee: 'ISPs should not spy or block sites'

Sir Tim Berners-Lee says he is against internet service providers (ISP) blocking sites or spying on web users.

"The job of ISPs is to provide good internet connectivity and is not to spy and not to block," he said.

The inventor of the world wide web told the BBC's Dave Lee that ISPs potentially have "a lot of power" to spy on web users.
