RICHARD: Well, you don't. The point is, you can't ever. So you just look at these different versions and you see which one you actually like. You can't keep the saboteurs out of non-free software either; in fact, the developer could be the saboteur. The developers often put in, as I said, malicious features. And then you're completely helpless. At least with free software, you can read the source code, you can compare the two versions. If you're thinking of switching from this version to that version, you can compare them and see what's different and look for some malicious code.
