Trying to take some of your customers with you when you leave is ... often a grey area. If they genuinely have more faith in you than in your former employer sans you, then it seems much harder to criticise. The problem, I think, is that anybody in that situation rationalises their point of view to that being true, even if it isn't. I don't have a good answer here, other than "I don't intend to ever end up in a situation where I have to make a personal choice about it, because generally I don't consider even grey areas worth while."
