You are almost investing in heroku by using their stack and tool chain, it isn't easy for well established customers to just up and move. This is probably a PR win for them, rather than a loss. Truth be told, it will be how they handle this in the coming months that will make them win/lose customers.
If you are locked in the trunk with any cloud solution , then you are a bad programmer/syst admin/whatever taking bad decisions, period.
