I guess if you don’t have direct internet access then sniffing wifi traffic at the local coffee shop might be the only way to get weather updates.

Not sure if this is what they had in mind, but certain very old devices won't cope with modern HTTPS. Old smartphones, for instance.

This may be a real concern in less wealthy parts of the world, but I doubt it applies to Australia.

One example would be running a client on hardware not capable of performing encryption fast enough. I think would be particularly relevant to web browsers on Amiga.

There's enough change in the ecosystem that outdated OSes (that people still use) often can't handle the current recommendations for which TLS versions to allow, don't have root certificates for newer certificates, ..., so how to set that up is an interesting balance if you need to reach as many people as possible (which for government info sites is probably the case)

* in China TLS 1.3 is blocked by the state firewall

* based on past reading of discussions here, in some states using encryption may be illegal, not sure if this is really the case, this may eventually come to the West as well, see Australia and U.S. officials attacks on encryption

* old computers/OS/browser that the user can't update
