Angry Birds developer Rovio allegedly rejected a $2.25 billion acquisition offer by Zynga over the summer. The report comes from a New York Times piece about how Zynga's tough corporate culture may gush talent as soon as unhappy employees with stock make bank on the IPO.

The piece also mentions how Zynga lost out on acquiring PopCap earlier this year for nearly a billion in cash to Electronic Arts, which offered a mere $750 million with performance bonuses.

Clearly, if Zynga offered more cash and lost to a company like EA (which had its own share of image issues in the past), it's not hard to contextualize that the Farmville publisher has a slight employee perception problem. At least Zynga execs can dry their tears with thousand dollar bills.
