Google co-founder Sergey Brin has warned of “very powerful forces” looking to undermine the openness of the internet, echoing Eric Schmidt’s concerns and admitting he is “more worried” than ever before. There are “very powerful forces that have lined up against the open internet on all sides and around the world” Brin told the Guardian, describing the situation as “scary.” He didn’t hold back on dishing out blame, either, citing Facebook and Apple as building walled gardens that do users – and rivals – a disservice.
