My guess is that MD wants to sell keyboards which generate a lot more revenue than sell a bunch of switches. After all, if they did a switch drop, per switch pricing can't be much higher than what the Hako switch sells for, given the similar genes, and their sales projections probably don't compare well against selling thousands of CTRL and ALT keyboards. Just a guess though!
I personally wasn't impressed with the Halo clear switches that came with my K-type. I sold it to a community member for $50, which at this point, regret given the high demand due to the popularity of the holy panda switches.
