Not mentioned in the article, but I'd also recommend force-setting DHCP Option 43 to "ANDROID_METERED" to let Android clients know you're on a metered connection (hotspot) instead of a normal landline-based WiFi network. [1] This inhibits some things like automatic updates. I don't know of an equivalent for other OSes, unfortunately.

No detection method appears to be present in Windows 10, it's all geared towards LTE modems integrated in the machine. I really wish this had been standardised.

For macOS you need to use an app like TripMode [1] or Little Snitch [2]. [1] https://www.tripmode.ch https://www.tripmode.ch [2] https://www.obdev.at/products/littlesnitch/ https://www.obdev.at/products/littlesnitch/

One can also use traffic shaping (iptables and tc) to dry up large downloads: https://unix.stackexchange.com/questions/229403/rate-limit-network-but-allow-bursting-per-tcp-connection-before-limiting https://unix.stackexchange.com/questions/229403/rate-limit-n... As anyone aware of even better solutions than this?
