Why do copyright holders get due process but not accused infringers?
Copyright holders are organized, e.g. MPAA/RIAA, and motivated (money moves ya). Content consumers are disorganized and little motivated.
I’m not saying this is right, just that this is the reason.
Just like if a law requires business to enforce mask-wearing, and then I get kicked out for not wearing a mask, that was not a legal proceeding. They just kicked me out.
