What we can get from the article thought is: why isn't gif replaced by webm/vp9 yet? Can be encoded in no time and is actually supported everywhere.
Apple has significant market penetration, and you can't get VP9 to easily work in safari/iOS/tvOS
Youtube serves h.264 to Apple platforms.
And yet, things continue to work and continue to progress for the most part, so format wars aren’t necessarily as big a problem as we like to think.
ffmpeg -i input.mp4 -c:v libaom-av1 -strict experimental out.webm
YouTube already has many of its videos encoded in AV1 up to 720p. Try it yourself with Firefox 67 beta, or any other browser which uses the dav1d decoder.
Turn on AV1 on YouTube (set it to "Always prefer AV1"): https://www.youtube.com/testtube
Try the AV1 playlist: https://www.youtube.com/playlist?list=PLyqf6gJt7KuHBmeVzZteZ...
Pick any popular video on YouTube (like a music video) and play it. Check the format with right-click -> Stats for Nerds. If it's AV1 the codec will be "av01".
On my 5-year old laptop, AV1 in Firefox 67 beta is fast enough for 1080p30 and almost fast enough for 1080p60.
