That does not sound extreme at all to me. It would not need to be controlled by people in elected positions - it could just be mandated that employees have to follow a specific charter and be as neutral as possible. A bit like many national news services, like the BBC. Considering how much influence Alphabet's products (especially Search) have gained over everyone's lives, I think something like that is much overdue and the only reasonable solution. That, or extreme regulation. At the very least, the search algorithm should be made fully public.
