Given that Google is the author of the main browser-based content decryption module in use (Widevine), and Google also has a bunch of content provider partnerships to maintain, and they run YouTube, which in some ways relies on content owners not getting pissed off and suing it out of existence (content owners are the reason YT has ContentID, not because of any legal requirement)... I don't think it's in Google's best financial interest to fight against DRM. So they won't do that.
