That's just the public report. It is perfectly consistent for a company to publicly say nothing wrong occurred, while quietly firing some of the few individuals involved. Personally, the sudden-ness and lack of reasons for firing lead me to suspect it was a reason. I realize this is unsubstantiated speculation on my part, so take this all with a grain of salt.
