It should be noted that those small number of websites are collectively responsible for most of the internet traffic today:

(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.
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.
