To their credit, at least they're still trying to build stuff. Microsoft avoids this problem by no longer innovating and just buying into whatever is trending. (Not that Google also isn't doing the same). If you never build anything new, you never risk killing a product that didn't trend, which happens a lot.
I think that if google wants to kill a product they should ask users to vote and not decide on there own. If they continue this trend they will keep loosing people to their competition.
