I think the sane argument here is for sensible defaults. Leaving all those switches turned on is just opening the door for adtech. The set of information that's made available out of the box should be small, and if you need to access information about my graphics card, you can ask for it.
I think this only works if the average consumer can assess what is being asked for, though. “Do you want to let this website know what hardware you have?” is not a simple question.
“What is hardware?”
“Should I let a game know my hardware? Should I let a news website know my hardware?”
It is a discussion how to do it right. And surely, if propertiary platforms can do it, browsers can do it too. Especially propertiary platform app has permission to the system data enabled on default. Browser asking for it, would make web apps safer than native ones
