Mozilla Foundation (non-profit) owns Mozilla Corporation (for-profit) which handles the development of Firefox, Thunderbird, Firefox OS etc.

Since when Mozilla has been non-profit? They are fully for-profit company. Just because they open source their products and generate revenue via Google instead doesn't make them non-profit.

You are the literally the product they're selling to Google and other search engines.

I really doubt that this is good direction. It's the greatest lock-down of all time. Every web-app (Google Docs etc) is behind the greatest DRM of all time, just like Blizzards Diablo 3.

The only reason this haven't ben discussed on Slashdot before is because it's been Google that has been developing fully browser based OS, and Google fanboys have de-routed every intelligent discussion about the merits of Chrome/Firefox OS.

Sorry, but in my opinion we must stop this development here and keep our native open and closed source apps. You can't even disassemble browser apps, all you have is the front-end. At least with Windows and MS apps I know they are going to stay around and work when I need them.
