Treating players, coaches and surroundings with respect is different from loyalty. Marrone and Ashton is probably still on the payroll because their wages are way higher than any other club wants to pay them. The same can be said about Llorente. I think you are being naive here. In the 25 years I have supported, Juve have always been tightly managed, with players coming and going, but with the only aim of winning. If you want to believe some fairytale band of brother story then go ahead, but dont start teaching me stories about what the goals and history of the club is and then get our facts distorted.
