For Monday's half-yearly results, anyone who attempted to join the webcast using Linux would have found a disconcerting message confronting them.
The message read: "We have detected that your operating system does not meet the optimal webinar specifications for listening to and/or viewing webinars.
"We recommend the following operating systems:Windows 10, Windows 8, Windows 7, and the latest Mac OS X.
Apart from a PC and a laptop both of which run Debian GNU/Linux, I have an old Mac lying around. But on trying to connect using that, I discovered that NBN Co only likes the new, shiny Macs.
From the start of the NBN rollout, NBN Co has provided enough evidence to show that it is somewhat backward when it comes to communication. That its webcast cannot be viewed on a Linux system just underlines that.
