The problem there becomes bandwidth. Its better, but upload speeds are still not great and sometimes I think that its intentionally done to help funnel people to using monitizable web services instead of just self hosting everything.
The reason why networks used to be symmetric is because ISPs believed users downloaded far more frequently than they uploaded and therefore a greater percentage of the pipe was dedicated to download channels. That increases QOS on bandwidth constrained pipes but comes at a traffic management cost. Now IPS figure if the network is already fast and the user wants it to be even faster then they can just pay for a larger pipe and everybody's happy.
