How is improving the specs of a standard a scam? It’s not like a phone that entices people to buy them with new “features” of questionable utility. Cables are boring! Most people don’t buy HDMI cables for fun; they probably only buy them when they get a new device or when an existing cable dies. And even then, who is going to shell out for an expensive version of a cable that they won’t utilize its capabilities? Most people buy whatever is cheapest.
I’m using Linux Mint (Cinnamon) with a 3070. I have absolutely zero issues.
