>And how long as the open web survived?

Since its birth, clearly. No matter how you try and spin this, advertising is not a requite for a free and open Web. If ads were to disappear tomorrow, web sites which society has deemed important will survive, the others (if income was necessary in the first place) will indeed perish. And we will be just fine.

Just because the open web is being murdered by Google and FB, does not mean we have to go along with their progrom. We need to stand up for what's right, not for what's winning today.

For a very, very long time.

That's because companies feel value in silos and extracting every cent they can out of users.

The open web never felt the urge to become walled before the ad peddlers made it addicted to revenue.
