Even the router isn’t really your ISPs job, I bring my own and don’t care. Of course some users are just going to do the easy thing and get Router and config from the ISP. But that’s less bad than DPI for example.
Not to excuse anything, but there’s a significant segment of reasonably computer-savvy users between “hackers” and the average Joe, who do know well enough what DNS is, just like they know what VPNs are and their use for streaming and the like.
