Most people have an unfortunate tendency to project their own values and preferences onto the world at large, and fail to recognize when they cross the boundary out of their own spaces and into other people's.
Recognizing this means advancing solutions that primarily aim to minimize conflict among many parties, each pursuing their own particular concept of the good within their own boundaries, and avoiding trying to universalize any singular set of terminal values.
Attempting to pursue solutions that depend on everyone agreeing on the same set of terminal values will always fail, and will often generate intense conflict that escalates well beyond the bounds of the original question and causes a great deal of collateral damage.
Yes, that's called compromise. It's basically one of the foundations of society and civilization. It's not a blocker for public-interest projects.
That's not what I'm saying, in fact 'perfect utopian' projects are exactly what I'm expressing skepticism towards. The problems we have with the internet are mostly just symptoms of deeper societal issues, and they arent infrastructure problems that can be easily fixed like a road or bridge with some massive spending bill. If the US actually enforced anti-trust laws and broke up the tech cartels it would solve a whole lot of problems with the internet, but I doubt that idea would get much traction with whoever ends up on the 'new internet committee'. And I dont see it as a lack of idealism, its just plain pragmatism
