Totally fair, but this alone by no means indicate that Chrome is more privacy-friendly than Firefox.
Firefox was the first browser to implement DNT (Do Not Track) alongside other major browsers in early 2011, whereas Chrome/Chromium implemented it nearly two years later at the end of 2012.[0]

Yet Google still has a massive influence over the project. For example, see what I wrote about DNT above. Chromium also syncs all your data to Google’s servers the moment you login to any Google service.[1]
