The most we can say Fictionwise are guilty of at this stage is a lack of communication. However, they've also got the most complex problem, IMO. In order to honour the spirit of their commitments to their Buywise club they would need to get the agency publishers to allow them to discount their books, which doesn't look likely to happen.
So Fictionwise need to get to the final answer on this, sort out their new contracts, perhaps talk to their programmers about what is actually possible going forward, etc.
They may not have said anything because they still don't know what they actually can say.
