I'm not quite as sour puss on Traveller as all this, but I understand where you are coming from. I do think Mongoose has been ramping up their efforts to provide better support and adventures. ITs pretty tough though as the market isnt really great for anything not named Star Wars. However, I find the less reliance on charop and strange monsters and beast, allows for a more flexible adventure telling. I spend a lot more time on exploration and social aspects of the game than I would in otherwise heavy combat focused systems. YMMV
Mongoose tried for the SW license...
Matthew knew FFG had gotten it, apparently before FFG's staff did.
Created quite a stir.
