So this is apparently the first case heard under the new version of s115A of the Copyright Act (we put in a submission last year).
The sites they’re going after this time are the ones where you paste a YouTube URL and get to actually download the video.
Of course if you watch the video normally, it’s already at least passed through your device, just not in a format that you can usually download. I reckon a local tool like youtube-dl actually ought to count as format-shifting, for example.
