Mostly the shoddy/incorrect/fake accounting issues that have gotten them in hot water with the SEC.

Actually, that is (in my mind) the biggest current one - the sales stuff is bad, but the accounting and operations stuff is Bad.

Presumably the board members are leaving because of a yet-to-be-public scandal.

The 'creative' accounting on their initial IPO paperwork was a scandal of sorts, but I don't think it left the IT blogosphere.

They talked a fair amount about it on Marketplace, a public radio show about business and economics. Still isn't exactly mainstream but its outside the tech news circle.
