Do not presume that pointing dns locally prevents passive monitors
anywhere along your network graph of clearnet hops from seeing your
dns queries there. And ultimately, exit IP can be observed and correlated
from the roots down with increasing difficulty. That said, yes, local is still
better, and often more performant, than pointing to a privacy joke like google.
