I don't see this as particularly unprofessional or petulant.
The owner/manager of the project didn't want to keep maintaining it and is redirecting users to an alternative that will work for almost all use cases. As of last month, there were reported flaws in TrueCrypt and there's nothing that forces a maintainer of a free project to keep going.
I'm left almost a little annoyed that the conversation isn't "RIP TrueCrypt project, thank you goes out to the maintainers for helping people feel more secure for years."
Alright, I'll play. How long of an explanation are the users of a free service entitled to receive before the maintainer can happily go his/her way without follow-ups? Development of Truecrypt stopped, and as it's open-source, someone else could keep hacking away on it.
