Because Cambium uses a distribution model that doesn’t allow for direct sale of anything with a part number directly to the end customer. Cambium relies on distributors to buy and stock inventory, handle customer sales, shipping logistics, returns/RMA’s, etc. By leaning on distributors to do this, Cambium doesn’t have to deal with a lot of the overhead associated with dealing directly with the end customer. If they were to start selling some or all of their products and licenses directly to customers, it would compete directly with their distribution network and destroy those relationships. There are pros and cons to both methods of product distribution.
