I disagree that this would have been the right thing to do. There's nothing wrong with explaining why something could be useful in an open source project - if the reason seems like something important that a lot of other users of the software would also need, the maintainers of the software might want to know about it so that they can add the feature or fix the bug sooner. It can also help if there's some way of working around the problem.

Calling the developer extortionate was unreasonable, but I don't think there's anything wrong with the first message.
