I'm listening, but I don't understand.

If you have an unequalled piece of closed software, why use an open one? The argument seems to be that you'd like the source so you can alter the program or peruse its source, but you can't do that for most OSS programs you use. There just isn't enough time.

So how is it any different from using a closed program? You'll never see the source anyway, and in the meantime you use a lesser program. Why? Just because it's OSS?
