It's frustrating. I wish a fringe toy for nerds wasn't needed for shit like this, although I wouldn't be surprised if Windows 10 sends similar analytics. And I say that having implemented analytics in the app start-up I'm part of. People underestimate how much a call home can theoretically do to tell you about your day, habits, and life. I'm also frustrated because I can't get pihole to work because I can't even forward ports on my ISP box. Gah.
I don't know what it looks like on that side of the pond, but on this side your ISP box isn't your friend. I lean pretty heavily into Ubiquiti, even though it's prosumer shit pretending to be enterprise-class and has a lot of really dumb omissions. I haven't used this shit but I've probably got $1800 worth of Unifi between home and work. Get a modem that will handle the speed, then put a router/WAP on it and control your life.
