Quite effective at destroying anything good left of Google I would say.
Google has a bunch of nice things (search, gmail, maps, ...) that cost money, and an advertising business that makes money, the former helping the latter. Split the two and the nice stuff will be without funding and die out, and only the "evil" part will survive. Or so I think. Splitting out Chrome will not change the face of the world, but Firefox has shown that an (somewhat) independent browser can work.
Those 'nice' parts of the google are feeding the 'evil' advertisement business. Now more than anything, the reason google's ad business is so rich specifically because they (and only they) know everything about most of the denizens to farm them efficiently and thus demand a premium. Take their feed away and the ad business livestock will suddenly be lot more docile.
