My ISP-supplied router tries to ping back to some “AI driven wifi analytics” bullshit every 30 seconds. I put in a custom block for that. My TV would also probably love to phone home if I connected it to wifi to use the applications on it.

The value is not just that I can block at the network level rather than the application/device level, it’s also that I can see what random connected devices that aren’t general computing devices are trying to do. If they have hard-programmed DNS servers, blocking 53 for any device besides my Adguard server quickly solves that.
