I think it's worth trying something in-between. I suspect an overarching economy has a lot to do with psychology and human behaviour, and I think its effects are great underestimated. It sets the culture. With linear, it's basically a tragedy of the commons when every individual is allowed full freedom so to speak. It detracts from society. A social content platform needs some collectivity, hence the suggestion to move away from linear, even if a little. n^2 was too much of a sacrifice of individual autonomy.
