Organic Search Engineers are not paid to increase revenue, any more than my company pays me to increase Field Sales revenue.
They do pay someone to do that, but it isn't me.
The fact that we are primarily an online entity, and Field Sales relies on the website to get customers is merely incidental. I (indirectly) generate the leads, they make the sale. We don't compare numbers, we don't have a combined strategy. I do my job, they do theirs.
We might not be a Billion Dollar company, but even we are siloed. There is no overarching strategy. Departmental specialisation is a fact.
That said, Organic Search and SERP layout are not going to be the same team. It makes no sense to imagine Google would willfully throw away revenue for a layout change. Similarly, it makes no sense to destroy usability by over saturating with ads. Crap user experience is going to drive traffic away much faster than a marginal decrease in search quality.
