We dont yet life in the police state where everyone's political opinions need to be hidden in dark networks.

Maybe you don't. I expect my country will turn into such a state mere days from now. A communist president will assume power next year and I have no doubt he will regulate the press and the internet to extents I didn't think possible. There's also a judiciary dictatorship installed with supreme court judges openly persecuting right wing political parties. Tools like these will be absolutely vital for anyone exercising political or intellectual freedom.
