Irrelevant for the point that was made on cheaper transactions. If Microsoft had accepted the payment in any other way it'd have left them with less profits on that particular transaction. It's relevant when talking about e.g. bitcoin as a store of value, but that topic wasn't raised. On that topic you could say that accepting bitcoin and buying a derivative to hedge, a bit like Bitreserve or Coinapult locks, would allow you to transact and store bitcoin, immune to bitcoin's volatility, yet cheaper than your average 3% Paypal, Stripe, Square or Creditcard transaction. Beyond that, it's merely semantics.
