The problem with "avoid crashing at all costs" is that the alternative is usually "produce invalid output". The latter doesn't sound so bad in theory - but in practice, it means that the resulting bad data can go quite a long way, further accumulating errors as it flows through the pipeline. Worse yet if there are any observable actions taken on the basis of bad data (like, say deleting a file, or deciding to show some piece of private data).
