>Have you even tried to turn that stuff off in Chrome?
Personally, I have made an effort to try to turn things off in Chrome, because I felt it to be a superior product to FF. I switched to FF purely because I realized that my interests are never going to be aligned with Googles.
The problem is with the rate of change, and lack of UI stability. Can you disable WebRTC? You used to be able to with an easy flag, now its probably harder. Can you disable WebGL? Can't seem to w/o jumping through hoops. Why is Chrome looking at my USB devices? Can I disable WebUSB? nope. Disable Omnibox? Dont think so anymore. You used to be able to IIRC,etc, etc.
Google is never going to make it easy for you to stop sending data to them. An option of "Don't send anything ever, and don't ask me again" would be nice. More and more UXs are employing dark patterns where disabling is never an option, just 'deferring' or 'pausing'. (e.g. https://myaccount.google.com/activitycontrols)
Its hard to make definitive statements because Chrome keeps changing. Now, thats not Chromes fault, of course, but what rate of change is manageable? I don't know.
