I completely agree with this. Even if you had the legal right to remove your code, or stall the site, (I have no idea if one would. I assume it depends on contractual obligations) and even if you decided that was your only rational option, it would still be best to handle the matter tactfully. A future client, even if they agree with your motives, probably won't agree with your self-righteous customer-service methods. That's not the kind of person most people want to deal with. Maybe I'm jaded, but my opinion is that, if your job/contracts require interaction with customers, then part of your pay is to compensate for having to gracefully handle the garbage those customers throw at you. That doesn't mean you just let people abuse you, but it does mean knowing your options, and calmly taking them, or, where you really have no pragmatic recourse, washing your hands and moving on. That's why I hate ever being in a financial position where I absolutely need the current client/contract/job to survive through the next week. Just my two cents, though.
