MacBooks recently had this bug that you had to connect it to LAN in order to initialize it, or return it to the shop. It's not all perfect in Apple world.

Still, Windows is a problem here. I wonder what the monthly fee is to get rid of the ads?

Not sure what you're talking about. Almost no one has Ethernet anymore. This would be national news-level failure.

A bug affecting M5 MBAs & MBPs made it impossible to connect to a WiFi network on the activation screen. The workaround was to use an Ethernet dongle: https://x.com/TheBobPony/status/2033958150936703363
