I was just a cog in a machine. The mindset didn't come from me but how they setup incentives internally and ran projects. To be clear, I ended up really resenting how it works and the advice was based on my experiences with trying to care (in fact I'm trying to get out of tech entirely). I ended up channeling my care and effort into building up coworkers rather than into the company or it's products and that's how I got through it for a while. Different people had different experiences though (it's a huge company after all), anything I say about my experience is very personal.

Edit: also if Google wanted me to really care about my job more than for self interest that relationship needed to be a two way street. The relationship of the devoted employee and disinterested company is common but to me comes across as a bit pathetic. I did a good job there purely because that's how I enjoy doing my job, if the company collapsed I wouldn't have shed a single tear (that's a lie, I miss the free food)
