Compare subscription to Netflix vs. buying a movie on a DVD (and maybe ripping a personal backup copy). The former is a subscription - you stop paying (maybe because of financial emergency), no movie. The latter is a one-time purchase, after which you keep the thing you bought forever (so when shit hits the fan, you still can cheer yourself up with your favourite movie.
I know I definitely prefer buying over renting/subscribing. Businesses prefer the reverse. It's a conflict of interest.
