Plausible, sure, but that doesn't mean it isn't a cop out. There are many things that Heroku could have done to prevent this, like delaying the disconnection when they don't have confirmed delivery of the notifications and/or when they are connected to paid dynos/accounts.

Thus didn't happen because of the contract, but because the people implementing this transition didn't give a crap.
