I don't know, that seems subjective. Marketing is part of every successful product so "hyping" is a key part of a product's lifecycle. Sometimes products don't catch on and they have to be killed. It's not any different than the plethora of startups that promise to revolutionize industries and fail to make a single buck. Supporting a zombie product isn't noble in my opinion. Those resources could go to trying something else when it's clear that there won't be any market penetration.

Google is not some fly by night startup. But people have learned to treat it like one and not depend on their products.
