NetworkManager is a top Linux application, available in each major Linux distributions and heavily used on laptops, desktops, and since Pinephone and Librem 5 - on Linux phones too. Networking and user privacy are important more than ever, and there are some questions related to the last.
MAC address randomization
Making suggested changes to default would break a lot of stuff. For example, enabling MAC randomization would cause connectivity issues if the user connects to a router with MAC filtering for example.
Or if your DHCP server hands out static IP addresses based on MAC. It would be kinda good for there to be a default-off “This is a trusted network” check box, which turns off the privacy preserving settings that can break things.
