Valid points, but I would add that they are now are having to change the pricing model as Perch as it is, is not sustainable which indicates something somewhere isn't working. And it's not always down to how you price your product or service.
This is of course all conjecture though, and like yourself and others have noted, Drew and Rachel are the only ones that know the details. Hopefully, if nothing else, this thread will help them decide on the way forward.
