Ok, batsman nicks it to the cordon, umpire doesn't hear it, he walks because he's a sporting chap and he knows he's hit it. Hurrah, isn't the spirit of cricket wonderful?Well of course it's cheating not to walk when you snick it - but it's acceptable cheating.
In other words, it's a bit like telling a 'white lie'. Lying (by definition) is morally dubious, but OK if done for the greater good, and no one is physically hurt as a result. Feelings are hurt of course, but who cares about those. The team on the receiving end of the 'white lie' should just get over it and move on.
Next week he middles one onto his pads. Up goes the fielding side for the appeal, and up goes the umpire's finger in response. Should he just stand his ground, and if not, why not? He's hit it, therefore he's not out.
