Has friend 2 set his name servers to something custom, or is he using your network’s default? My partner uses an iPhone and it has some sort of built in DNS so she doesn’t benefit from me installing DNS based adblock on the network. You could see if a similar thing is at play.
To add to this. While there is “more information” that information is increasingly locked down and unsearchable. Things that used to be easy to find are now hidden in the walled gardens of sites like Facebook, X (Formerly Twitter), etc. Google Search and similar engines basically only searche ads now as everything else is locked down. It’s an internet full of data… that we can’t easily access.
