Another main reason...
... was that it took Six Apart's team some two days plus to post any kind of information whatsoever on Livejournal, citing 'they were on the road and were checking things'. This would be the same two days spent conducting phone interviews with CNet or running around on digg-a-like sites (Metafilter, etc.) posting on comment threads and forums trying to clear their name.
Note 'information' in this case includes the simplest of messages saying 'Watch this space'.
While theoretically they were entirely in their right according to their TOS - standard 'can delete for any reason' boilerplate goes here - the corporate handling was pretty abysmal, with their responses on forums often inflammatory or completely inaccurate - at least one sparked a row by saying something akin to 'Our policy has changed, full stop.' which... turned out to be completely erroneous.
I also might be wrong, but as I understand it WFI tried to sidestep the 'veteran' Abuse Team (who would, one assumes, have taken one look and gone 'you what?') and went straight to Six Apart, for the less technically-experienced team.
