The difference is Google pay Mozilla to be number one in the search box and, I believe, when people use the search box whereas Chrome begs you to login with your Google account so it can link every god damn thing you do in your browser with your account. Google didn't make Chrome for any other reason than it gets them more and more data. Same reason they made Android and Google+ and Gmail.
Doing so would be great actually. Buying licenses for Windows in order to build and test Windows builds cost money at the end of the day and free licenses make it a little easier for the developers and testers.
Seriously, you spell the guys name wrong in the god damn summery?!
Wearing headphones is essential for allowing me to stay "in the zone" when working on a complicated task. A lot of the time I don't even have music on I just wear them to cancel out the background noise of people talking, phones ringing, etc. Everyone I work with knows if I am wearing headphones and my internal IM is set to Away then fire me an email and I will get back to them as soon as I can and I am very grateful they respect that. Obviously if there is a "big issue" then I am fine with being interrupted but that happens maybe once every few months. I was very clear with people I work with that due to the difficulty in some of my work I really need to be able to keep my concentration locked without distractions if they want me to work efficiently. I am lucky that I work in an environment were people understand and respect that.
Having worked at several blue chips all anybody cares about is the appearance of security (i.e. security theatre) enough to cover them for audits and compliance. There is no real security in place in most places. Like you say security is hard and expensive. They don't want to make life harder than the minimum.
As someone who is just getting back into Java development the security issue of the past few years have had me a little worried. This is a great step in the right direction. Kudos to Oracle. I hope that the work they are doing on the browser plugins in Java 8 improves on this. On a kind of related note; IntelliJ IDEA is a freaking sweet IDE! It isn't quite up there with Visual Studio but it makes working with Java much nicer than it was a decade ago!
