Who is "us"?
The internet is available to more people in more countries than ever before. There's more content on the internet than ever before. It's a part of every day life for nearly everyone in the world.
That's what's happening to the internet. It's no longer a corner where quirky tinkerers were the only ones who could access it.
And the promise of the internet was never to be just that.
It was meant to be a vehicle for humanity (along with all it's warts). That's what you're seeing. The rest of humanity coming on-line.
The attitude of "this isn't what it was meant to be" presumes that it was meant to be anything at all. Similar to a kid that doesn't want to share their legos with the rest of the class.
