That doesn't matter. At the end of the day, for each query, there is produced a single ranking.
Given access to the data, or more ideally the ability to rapidly batch query, one could ask does being a google owned or rev-share site affect rankings? And if so, up or down? These are the questions statistics is made to answer.
edit -- and it doesn't even necessarily need be hardwired. For example, google could have more visibility into site interactions on google owned or tooled (GA) sites, and that could tend to lead to lower serps. Ie just the presence of certain features, only available to google when google owns or tools a site, could tend to produce lower ratings no matter what those features are. This is, I would argue, dirty pool for what is effectively a monopoly. And statistics can answer these questions.
Imagine if latency was one of the signals Google used to determine ranking. Now imagine that Googlebot gets a ping of half for an application that uses Google App Engine as opposed to someone who uses a raspberry pie at home. Would you say that the makers and users of Raspberry pie now have grounds to sue Google for ranking them lower?
Raspberry Pi was a poor example for him to use, but App Engine (or any Google Cloud solution) was a good example. The Google-hosted sites (including the properties Google owns & operates) will always seem to have lower latency to Google versus everything from AWS down to a Raspberry Pi in a basement. Should that be considered an unfair impartiality in Google's algorithm?
Lower latency to google should have no bearing on serps.
Lower latency to the user should. If, ceteris paribus, google sites are lower ranked then yes, that should be illegal. ie consider regression and compute I[google] + site_speed; after controlling for site speed, being a google owned property shouldn't matter. It's fine if google owned sites tend to be faster and hence are more lowly ranked.
I specifically meant more along the lines of google can view your navigation through GA tooled sites, and there is a wealth of information that can be derived from that.
