I'm certain that I ( and others ) have posted about the existence of Wireshark in the past ..I think I even mentioned it before in relation to what Chrome gets upto..
I was following the other thread, and did think of mentioning it again in there..but didn't really have the time to get into the inevitable "no they don't" / "yes they do" arguments that I anticipated would follow..( it was a busy 10 days or so for me with other stuff )..folks here like to try to put one 100% into the G fanboi or G haters boxen..never thinking that there might be other boxen.. sometimes trying to spread a little light and get a little thinking going gets wearying :)..TMS and some others who don't post much nowadays knows what I'm talking about ..
Chrome was "given" to the world for just one reason..( detailed tracking of what people do on a page by page basis ) and the built in default browser on android mobile devices does very similar..( although it can't track mouse movements as they have no pointing device/ mouse )..this is why Chrome runs autonomous tabs..each tab open is a distinct interface..what you do within it and whether the pages call double click etc, or your mouse hovers over this area or that area, whether you scroll the page or not..all is available to be phoned home..
As each tab is separate it is easy to ID which is "in focus"..so open tabs that are not being viewed do not "screw" the data..
They launched chrome in 2008
that is 4 years worth of data.( they "open sourced" "some" but not all ;) of the code later..the important parts are still not "open source"..
4 years of data..25 to 30% penetration as the browser on desktops ..multi platform..runs as a different version as default on all android phones and web capable tablets..
Is being constantly silently updated in android devices..
They have the means to gather all the data that they need,( without using Ganalytics) and they have done so, are doing so, and use/d it..( not in the "main algo"<= they were careful to say that..but there is no longer really a" main algo"..so that denial was semantic sidestepping ) ..How many android users change the default browser ?
Why did they make an addon for IE ?
