> This works for future customers, since once Heroku makes these documentation changes, everyone who signs up will understand exactly how routing works. But it does nothing to address the time and money that existing customers have spent over the past few years. What does Heroku owe them?

Lawyers -- well, judges really -- are good at coming up with answers for this exact sort of question.

I am not being facetious. There are legal rules for assessing losses in even very complex, very entangled situations. If you feel Heroku has dudded you, find a torts lawyer.

Heck, Salesforce.com have deep pockets. Round up a few other $20k/month customers and start a class action.

Web companies need to realise that boring old-fashioned rules like "your claims should not be misleading" apply to them too.
