To play devil's advocate here, this could mean that sites will stop loading 50 different scripts just to show an animated newsletter sign-up box or some other fancy shit. I mean for the love of God a lot of modern web sites look like an amusement park. You install uMatrix and everything is considerable faster. Web devs have really dropped the ball. I don't disagree with the main sentiment though that this isn't Google's problem to fix or even their right to intervene, but even if it's fixed as a side effect I'm fine with it.
