The products work like so: you can buy them and not put the switches in the dark pattern mode (Not called that). Or you can flick on the switches and make the experience of rejecting 3rd party cookies annoying and unlikely. Called "optimizing visitor experience mode" or similar. And companies that buy them obviously want to do that.

Are they aware that this is when they stop complying, to the point that they could just as well have ignored buying the banner service and just shoved cookies on people quietly like they did before? Perhaps. It's possble that lawsuits could work here too. I'm (like you) guessing there is some fine print saying that you absolutely cannot use the switch that makes the "reject" button disappear under the mouse and have a delay of 60 seconds. And if you do then you are responsible yourself.
