It is clear when you're on a browser that your search terms and text inputs go to a server somewhere. And RMS has plenty of warnings about such things as Google Instant, Facebook "likes" and other sneaky ways websites spy on you.
But at least up until now you could stay away from that stuff by just not opening a browser, and you knew to be careful when you did. Now there is no line, just "be careful what you type on a computer, period. You don't know who's watching". And that's a lot worse. What if your private journal on your hard drive is mined for targeted advertising? No, keep the web and my desktop separate, that's the point.
