Berners-Lee: the most popular services are bad for the web

Candy and soda might, under certain circumstances, have a negative
impact on an individual’s health. But most of us would probably find it
ridiculous to state that candy and soda threaten the existence of the
human race.

The man who invented the web, however, might be accused of making an
equivalent argument when it comes to the web’s version of candy and soda
— all of those ‘closed‘ services so many of us love, like Facebook and
iTunes.
