(1) Those numbers do not make distinction between Youtube/Vimeo (no DRM) and Netflix/Hulu (DRM). As an anecdote, none of my friends watch Netflix on their desktops, so while they spend plenty of bandwidth, none of them requires Widevine.
(2) Those numbers are bytes transferred, which is hardly a good metric of user importance. If you look at "top 100 websites" reports, like [0], you see there are no DRM-only sites at the top -- Netflix, for example, is on position 25.
The project I built and mentioned in the article, Metastream [1], is used to sync videos across browsers. It now lives as a browser extension and I'm able to track which web domains are most commonly used by the app.
Based on the usage statistics for the past month (28,711 samples), these are some commonly used media websites:
1. www.youtube.com (69%)
2. www.netflix.com (5%)
3. www.crunchyroll.com (2.5%)
4. www.hulu.com (0.8%)
5. www.funimation.com (0.3%)
6. www.disneyplus.com (0.3%)
7. other (22.1%)
The app is heavily skewed towards anime which already has a problem with piracy. That said, we can at least see that approx. 9% of traffic in my app is for DRM-enabled media.
Personally, I don't think the usage statistics of DRM media matters much. It shouldn't be a requirement to consume any content on the web to begin with.
