XP SP2 made the firewall default and enabled. If Chrome disabled it for themselves and started uploading user files when the computer was idle, will that make it okay since it was Microsoft who installed the firewall by default and not the user?
MS tries to market their browser as safer and with more privacy features. Presumably some users trust MS to go with safe defaults. And Google tries to break that by intentionally breaking the standard for their profit by recording the users' browsing habits on their tracking servers and you are sympathetic to Google because they would make less profit if they didn't do this?
I recognize it's a judgement call, but I'm sympathetic to breaking P3P because P3P is a crappy standard that doesn't actually do much to protect your privacy. In 2012, P3P is best known as the thing that breaks your single sign-on solution in IE.
