> I wondered: why can't I use my phone's LTE data to hotspot?

I heard of this 10 years ago, but is this still the case in the US? You can't just hotspot? I thought iOS and Mac devices did this automatically when they were near each other.

So, regarding the title: "support" is used euphemistically here to mean "permit" (an editorialization not present in the article). This euphemism is usually used by companies who want to de-emphasize their exertion of control over you - Apple is particularly fond of it (as when they say they do not "support" downgrading iOS - there is no technical restriction, they just don't want you to). Here, though, it seems to be to de-emphasize the "rule breaking" nature of this hack - the original title is far more blunt: "Bypassing hotspot limits on iOS".

It is interesting that this hack is entirely about defeating a conspiracy between Apple and a network operator to control what goes on beyond the netop's endpoint, and it does this - barely - by exploiting the fact that an iOS device is still a general purpose computer despite Apple's best efforts:

This is not a good reason.

Thanks for sharing!

> When you use a hotspot on iOS, your device treats your hotspot's network packets differently than the network data that apps use. Hotspot packets get routed differently, and they get metered

The OP doesn't mention it but it looks like a case of where the operator monitors TTL of packets to detect tethering.
