Google can control both ends of the pipe, which means whenever they make big changes Chrome users will have a better experience. They pushed ahead there with MSE, codec support (VP9), SPDY, HTTP/2, etc and other browsers had to catch up. If other browsers were ahead in some areas, it didn't matter, because the content side didn't support it. Sites are designed and optimized in Chrome first and foremost, so Chrome never risks looking slow.
Similar things apply to Safari on iOS, or Edge on Windows.
The problem in my mind is that by having the same parties sit on both ends of this story, it's inevitable the middle man (that could be a leverage against DRM) gets pushed out. It's very, very hard to explain to the majority of users that they have to accept short term pain to avoid an outcome that is much worse for them. Ask any politician.
But we don't even need to kill the web to get there (pushing out any middlemen). We have native apps! Nobody is complaining their Android or iOS phone has DRM, do they?
