Unless they actually convince Linux to block non web apps, you could run whatever you want on a FOSS platform, you'd just be able to run proprietary web stuff in addition to native free software. I'm guessing eventually the native free software would move more and more into the browser too, but that's fine as long as you can still run the stuff that hasn't been moved yet or isn't interested in moving.
