by doing this, they are laying the blame on one person so the media can stop hating Digg and start hating the ex-VP of Engineering who "killed Digg".
of course, whether he was actually responsible in some way is something we may never know. for all we know he may have been completely against releasing v4 but was vetoed by Rose et al. or on the other hand he may have overpromised and under-delivered, putting the company in jeopardy, in which case he deserves to be let go.
it's all speculation until we hear an official comment from either side.
The typical investor doesn't take the time to really understand the companies or technical issues, unfortunately. They see 'there was a problem, management fired the guy who was at fault' and are happy.
