I call the Iron devs shady because they do things like this.
This is one of the things they list as something they remove from the Chromium source code for privacy reasons.
and this is what a Chrome dev says about that.
Furthermore, the "URL tracking" mentioned both on IRC and on the Iron website refers to the GoogleURLTracker class. This unforutnately-named class figures out whether to use google.com or google.es for searches from the URL bar, and does not in any way do any sort of spyware URL monitoring. This is obvious to anyone who can read code, and should be obvious to anyone technical enough to produce a product like Iron. At this point I can't believe they're doing anything other than being intentionally misleading.
This serves as a good example of the sort or significant effort we've put in to make Chrome be privacy-conscious and Google-independent. Half of the bullet points on the Iron "feature" page are options that can be turned off in a clearly-marked "Privacy" section of the Chrome options, and the other half are misunderstandings like this one.
This same page details an IRC chat that shows the Iron devs intention with the project were merely to cash in on ad clicks
mgreenblatt - Iron.. why not propose a patch based on preprocessor defines that disables the sections you dislike without forking the code?
mgreenblatt - (assuming such a thing doesn't already exist)
Iron - because a fork will bring a lot of publicity to my person and my homepage
Iron - that means: a lot of money too
jamessan - heh, you're expecting to make lots of money from making a fork of chromium? that's quite amusing
Iron - i dont take money for my fork
Iron - but i have adsense on my page
Iron - a lot of visitor -> a lot of clicka > a lot of money
All of which explains all the bookmarks and iron-start.com homepage leading to their ads they stick in Iron
