I will add, for those that lost the plot: the goal was, and still is, to build a world where anyone can communicate with anyone else without exposing their physical identity and location, and therefore people cannot be physically persecuted for what they think and say.
We're far from achieving this goal, and we underestimated our opponents by a lot. But it would be foolish to blame the Barlows of the world instead of blaming the tyrants and corporate opportunists that go to great lengths [0] to sabotage and interfere.

It was probably a bad goal anyway. Anonymity turned out to be a great tool for fascists, and privacy is not going to save anyone if the fascist shit properly hits the fan.
The unfortunate reality of the internet is that anonymity is abused by troll farms and genuine human interaction is corrupted by their astroturfing and political propaganda. Anonymity in the hands of the powerful is so much more corrupting than the liberty it imparts to the weak.
