It&#x27;s not about belief really, it&#x27;s about necessity. At google it basically rains ad money 24&#x2F;7, that plus backbone internet traffic is where the vast majority of their money comes from, and it&#x27;s a ton of money. For everything else it doesn&#x27;t matter if it&#x27;s successful as a business or not. In fact, the best case scenario is mediocrity and barely breaking even in terms of costs. Because that means there are no consequences, no bigger implications, no expectations for improvement, etc. Google is sitting on several enormous multi-billion dollar businesses (youtube and office tools, for example) but they don&#x27;t care to actually develop them into such. Right now they can afford to not care, and all of the internal incentives are aligned to promote not caring.
