I, for one, prefer the subscription model for some things. I like that I can dip my toes in and out of the Photoshop ecosystem without having to shell out hundreds up front. I prefer to rent Netflix for a month rather than purchasing DVDs or Blurays I may watch once or twice. And when cloud gaming is baked (it will be a long time away for me as I live in a small island nation) I will love being able to play any game from a huge range with no outlay other than my monthly subscription - no hardware requirements, no upgrading, just a few bucks a month, and only on the months when I choose to keep my subscription.
My only caveat with cloud gaming is that mouse + KB is non-negotiable, I'm not sure how realistic that will be. I will not play shooter or strategy games with a controller.
