You mad, and I am not your dog.
Get your facts straight
They put it out under their name, they contracted for it and supervised.
In fact, almost every RPG is contracted out. Most don't stink.
Bull. Quite a few are author-publisher.
CT wasn't, nor was TNE - both design teams were GDW-in-house.
Certain companies have a history of outsourcing to independents, but they are not, in fact, anywhere near as many games as "most" - keeping in mind the number of indie games released in the last year numbers in the multiple dozens, most published by their authors, and a few by co-ops (like Diaspora and Hollowpoint, Published by VSCA, whch is a coop including the author of those two, Brad Murray). Lamentations of the Flame Princess is written and published by Jim Lot; he's only recently started hiring others do to work for hire.
To be blunt - there's as much, if not more, to dislike about both CT, TNE, and T4 as there is with MT. GDW has had errata for almost every game I've ever puchased from them, before contracting out to a talented group of amateurs who did a very popular fanzine and a couple nifty licensed products (Grand Survey & Grand Census). Kenzer and Co do all their core books in-house, too.
Oh, and MGT didn't contract out the core - Gareth was, at the time, a staff member at Mongoose. They licensed the setting, but much of their initial work for the Traveller line was in-house work by staffers. Mongoose's Mercenary was also done in house, and their High Guard.
D&D is done in house. Hero Games had Mr. Long in-house for years. RTG's core books were done in-house.
In fact, the companies best known for freelancers are SJG, FASA, and WEG. SJG still does corebooks in house, while FASA and WEG are defunct.
Many companies hire freelancers for supplements, not many for core rules. GDW doing so was an oddity.
