I blame Apple

Until recently (2 years) there has not been a device or a network that
could 1. Browse legitimally and or
2. Handle the traffic

I had a buffalo wireless network eight years ago. The speed was great
but there was no content and the content that existed was not
compatible with the browser offered.

Apple creates a product that for the first time allows a user to view
their favorite content.

Realistically it's going to take time to meet the network demand.
