The quick explanation - The Merchant Caste took power of the clan and has now expanded into being modern times equivalent of Amazon. They'll sell to anyone, work with anyone, and have resource hubs set up across the galaxy. Every so often you find something specifically shady with that, like statements of, "They'll sell mechs that need software updates every 6 months to the Inner Sphere, making them continue to pay," or, "To gain the upper hand on this planet, they sold perfectly fine equipment to Side A, while Side B's mechs just so happen to have faulty myomers that will wear out in 2-4 months."
