But then the VPN product is the revenue driver, not the browser. You still aren't making money off the browser. The whole point of the article is decrying the lack of focus on browser in order to focus on other revenue streams. I don't think one other other revenue stream is the solution.
The money would go towards the browser, just like the person suggested. How is that a bad thing? Maybe some nice mods like VPN, excellent RSS feeds, power user addons, etc for a couple bucks a month (or $5? )
