Do Microsoft want to sell their phones to as many people as possible or only a select few who would prefer to be on Spark? Maybe Spark bids for the phones so they are the only ones selling them?
I don't know how it really works, but in this day and age, wouldn't it be better for Microsoft to have the devices in as many stores as possible at launch so they are covering the market? You can walk into any tech store and pick up an iPhone 6 or a Galaxy S5 that works on Spark, but if you want to look at or buy an 830 from anywhere else you can't as its Spark stores only.
