I think that they mentioned that was just the publishing rights for FA or something, SE owns the SupCom license.
Actually, I think Kings and Castles was that reason. They started a cool project that everyone was excited for and then just abandoned it out of the blue. I think everyone lost faith in them, and wasn't willing to trust them enough to hand over their money for another project - they feared that GPG might just abandon this one too (and ultimately they did, although this time they had a reason).
Unfortunately I've had to deal with the way WG treats their player bases, in particular the disregard for the EU servers and somewhat for the NA servers. At the end of the day WG have been spending a lot of money recently and now they want to start getting some back, hence this: http://ftr-wot.blogspot.cz/2013/03/gas-powered-games-work-on-f2p-mmo-for-wg.html Its also suggested that they are cost cutting (recent updates containing reused models) probably due to the their investments in GPG and other projects. Only time will tell what happens here but I'd say that WG are looking to to what EA did some kind of F2P MMORTS.
