Each team has their own incentive:

The analytics team - get the best data possible The page speed team - get an objective analysis of the speed of a page

Even if it's in Google's interest to give their own stuff preference that would probably require some director or VP to coordinate that collusion and it's hard to say whether it would be worth the liability of having done that.

I don't think it's so much wanting Google scripts to have special treatment, but pushing the script teams to prioritize performance too, just like the Chrome and page speed teams.
