I think hiveage acted professionally and remained polite to what, by all accounts, appears to be a bit of a dick with a chip on his shoulder: "Build your product the way I like or I am going to make your life as difficult as possible and give you bad PR"
We get the odd client like that. They get a lot less than 7 days...
While it's OK for Hiveage to say no to a feature (that's what I could gather from what's there) the right thing would be to give enough time to export.
Also their road map looks more like "previously on hiveage"
