They are not doing independent studies. "all four recipients plan to collect data directly from broadband providers" -- Democrats are not Socialists any more than Republicans are.
"each also described plans to collect or utilize data from other sources. Examples include wireless propagation models, speed tests, online and field surveys, and drive testing."
I have a feeling almost all of their data will be from this, as the incumbent providers aren't going to give it up, no matter what is said in some description or plan.
