They know what's real because the company I used to work for (RootMetrics) did those drives, and sold the data to Verizon, et. al.
This could have an influence on 5G roll-out since US carriers are heavily indebted. If that's inhibiting capex and if the US network is already behind other nations' carriers' LTE networks because it was starved of capex, US carriers might be extra cautious about spending on 5G, which is supposed to raise opex, too.
