Sure, but that's nothing special. Any measuring, any science is done by people with the usual biases, that's hardly a reason against doing science and acting on empirical results. In medicine, law, economics there's always heavy political biases but that doesn't mean making judgements based on data is worse than making no decsisions or just making our preferred conclusions up. This rhetoric is exactly what I meant when I said free speech has quasi religious status. A perfectly normal, obvious fact, that measurements and decisions are made by biased people is presented as an argument to put free speech beyond questioning or a science based approach.
