I value loyalty as a behavior because it establishes stability. It offers predictability in a world that's changing ever faster. However, we have to be smart about our loyalty. In order to have a stable base from which we can handle change, we must build our platform carefully. We also have to inspect it and maintain it. When loyalty tries to consume us, or to move us around, it must be questioned and possibly removed.
Loyalty exposes us to exploitation. This situation reminds me of the old saying "It's good to have an open mind but be careful that your brain doesn't fall out." I would say, "It's good to be loyal but be sure you don't become a pawn."
