I think the pirate scene will be the first, which will take AV1. They always are very advanced in terms of technologies. AV1 is just a very new codec. You can use it in the Web for Chrome and Firefox. But it is too early to use for downloadable video files. For video files you need a OS support. Microsoft has it only in Beta. Android will support it in Q. Linux supports AV1 already. I think in next year we will see more and more AV1 everywhere, including pirate torrent trackers.
