I just had someone here accuse me of being part of an astroturfing campaign because I disagreed with them about FOSS licensing. At that point I just stop responding because there’s no use having an argument about whether my entire comment history is just a facade to cover for my secretly paid-for opinions about FOSS.
I think that the “post-truth” world that is blossoming in Right-wing political circles, where incorrect facts are hand-waved away as “differences of opinion”, is causing people elsewhere to react defensively and be very guarded against any actual differences of opinion, and some are overreacting and treating any difference of opinion as immediately suspect or even malicious.
