Disagree. Turning subscriptions on/off (assuming that doesn't require phoning in) seems much easier to the layperson than figuring out how to torrent something without getting viruses and/or copyright strikes.

Remembering to turn subscriptions on and off is where the pain will lie

Use reminder app on your phone?

I do it. I'm sure a lot of people do it Nd will increasingly as number of services grows...

Quit watching your favorite show for three months? I doubt many people are willing to do this.

The Witcher had a complete series drop recently: sign up for a month to watch it, then cancel. The Expanse is going for a weekly recently schedule: once it's done in January, cancel the service.

Unless there's a continuous series of releases that people will want to watch, I'm not sure they'll want to subscribe for an entire year: it surely adds up.
