> As far as I know, current ad blockers can't block ads from Widevine (DRM protected) streams, so I guess it's only a matter of time until Chromium team comes up with Widevine for webpages and then it's game over for normal consumers.

Only where the the adverts are embedded with an encrypted single stream.

Hard to do targeted advertising that way though.

It is a lever that you can pull that's better than nothing though.
