After reading the e-mail (I haven't seen this at all before, so I have no opinion about their communications and what has happened in the community), this reads to me like it was written by someone who is frustrated that their plan of how to do things wasn't understood/respected and is now fed up with the entire thing? Seems a bit weird, but I think it could totally be genuine (probably result of failure to communicate). And if money has changed hands for access to a product, they'll probably have a bunch of refunds to issue? (depends on exact terms of course)
