Google isn't concerned about fixing the issue because they're a group of semi-academics and overly ambitious managers. The result is that they can't close a project even when dozens are in alpha/beta, and they will definitely rather muck around on some novelty thing than produce an actual "boring" deliverable (like bughunting their browser).
See also: Android. A tech nerd's dream, but only attractive to budget-minded consumers. They could make it great, but that includes doing "boring" work, like bringing their stock email client up to speed, or enforcing standards in their store and with their network partners. Definitely not what their top-of-the-class CS-grad staff want to do.
A few marketing guys made Google successful by insisting that their interface be as clean and ad-free as possible, which was novel back in 2004, but since then they've been slowly creeping up to Yahoo-levels of spam and MS-levels of rude snooping. I expect in another 10 years Google will be just another "tech" company getting money from a de fact monopoly, and then giving it to their own bloated, unproductive workforce.
