Users were angry that Sandbox made the announcement so close to the Fantasy Football season. I imagine that they are even more angry to find out that Sandbox, in an attempt to avoid bankruptcy, (1) duped members out of a couple months' worth of Peak Usage access when the fantasy football season on Sandbox was doomed, and (2) sold every user's email address to an internet marketing group (they emailed all of us an announcement.
I understand that Sandbox was doing everything it could to stay afloat, but unfortunately it alienated it's longtime users in the process. The quality of Sandbox's product has decreased exponentially in the last year and a half, and the Peak Usage Program was the straw that broke the camel's back for a lot of folks. It looks to be a clean break between Sandbox and its users-- Sandbox can no longer operate profitably, and subscribers no longer care.
