A) you're wrong. Google is still almost completely ads as far as profit is concerned. Still almost 97% of all profit Google takes. Google is ads, whether you like to think that or not.
B) Why should any of us care if there are human engineers doing human things behind any of this? Are you trying to throw a pity party here? "People are vocal about their concerns." That sounds like whole lot of, well, concerned people. Good for you. The occupy Wall Street clowns were also very concerned. And a minor irritation for a lot of people who were not the 1% but were just trying to get to work.
I honestly put about 0% of interest into people who say they are concerned about anything. If it's really that important to you, get off your ass and do something about it. Otherwise I really don't care. And here's the sad truth for you: no one cares about what people are concerned about. Not a single person. No one at Google, and no one anywhere else. No one. No one cares who is vocal about their concerns. Not us, and not the management at Google.
I walked away from the highest paying job of my career 6 months ago because I thought they were making bad decisions that damaged people's lives. I was vocal about the bad decisions before I quit. I was ignored. And that's all fine. I lived off savings for a while, and then I ran out and had to do odd jobs and even some manual labor to float me until I landed a new gig a couple weeks ago.
You can do that too. You don't have to do what I did and walk out of a meeting and not go back, but you can do this. If you really think that bad decisions are being made, the only meaningful way of making your voice heard is to not work there anymore.
Until people start doing that, literally no one cares about what you think or if you're concerned or voicing your opinions. The only things that matter are the product decisions your leadership team makes.
I suspect you are a sincere and caring person who doesn't like every choice that Google makes. That's wonderful. So do something meaningful about it. Stop making those things happen.
