The value could at least be support - this to me would be the minimum expectation for any type of enterprise software, but amazingly it isn't offered in any of their packages (they just state that documentation = support!). Even in smb & enterprise plans it is "pay for a bug fix if you find a bug".

It is amazing to me that they expect a paying SMB user, who has discovered a bug in the code, to pay £12,000 for them to fix it! Then they wonder why nobody signs up - what a joke!
