Same here. I have Prime but only for their Amazon Prime delivery services, not for their video or audio thing(Amazon refuses to unbundle their stuff in my country). To make it worse, Amazon Prime Video, Atleast last I tried didn’t go to full HD(or even 720p) on Firefox on Linux, so there is no point to it.

And there is hardly an ethical concern to it. I am paying for a service but getting my hands on the material; just via a different supply chain because Amazon sucks.
