I'd like to add that accessing your things from outside the home is relatively simple if you have a static IP and you setup a VPN to your home with Wireguard.
Some advanced routers even have native support for Wireguard, like the Freebox in France or the Iliadbox in Italy.
It's because they don't want to break compatibility with existing software. Which I understand, because if they broke old software then people could just migrate to Linux as well
The Do Not Track header has been discontinued by most browsers. It's the sad state of affairs.
In an ideal world, all websites shouldn't even show a cookie alert if you have that header on.
