I think maybe they're bemoaning the dichotomy between increased access and apparent decreased use of the internet for creation of content by ordinary users -- or at least content that's not being exploited for advertising/marketing?
I'd warrant a tiny fraction of users have their own blogs now compared to a decade ago?
But that was apparent from the get-go. Most people just want to consume. In the early years, "going online" already took some effort or knowledge - only as it became gradually easier did the large swathes of consumers join.
If you lived through Eternal September, you kind of knew this was coming.
But again, just because plenty of people consume, and plenty of companies cater mostly to the consumers, doesn't mean there isn't another world out there for those who look.
