I'm actually a little surprised that, some discounts for annual subscriptions notwithstanding, the streaming services haven't done more to discourage short-term jump on/jump off subscriptions.
But they have the data and I don't. I assume there's enough stickiness and inertia that most people are not canceling and restarting services all the time. I know I don't. I just decide I don't care enough about most content (and don't really watch much video or binge watch anyway).
As you say, most users probably don't bother stopping/starting subscriptions. Besides, if they make it harder to cancel some users might not subscribe in the first place in fear of being locked in.
They're probably making more with users saying "I'll subscribe now but cancel when I'm done watching this show" then don't bother cancelling.
As much as people complain, maybe if I was still 22 and dirt broke, I'd do something like that, but more likely I just wouldn't watch TV. I didnt own a TV back then and it was fine. Now, sure, I don't exactly like being nickle and dimed from a pure intellectual perspective, but these streaming services are what? Like $15 a month a pop? That's 1/40 the cost of groceries. It's annoying but makes no difference and isn't anywhere near worth the hassle of starting and stopping. If it was a $120 a month gym subscription or the old cable bundles I used to pay $200 for, then it's getting to the point that it's worth caring about.
The stickiness is probably just that. Even as they raise prices, it's still less than we're paying for pretty much anything else. Gas, electricity, food, housing. Cut Netlix and well great, I just reduced my monthly spend from $5000 to $4980. Really making a dent there. I can retire comfortably now. It's almost as patronizing as the old avocado toast thing. Avocado toast might be overpriced and nowhere near worth it, but it isn't the reason anyone is broke.
A big part of the reason I keep my Paramount+ subscription month-to-month despite mostly just watching Star Trek on it is that they sold me a pretty good annual plan discount.
Annual plans are a big factor in the stickiness of Amazon's efforts. Especially with Amazon's dark patterns around trying to make people forget they pay it (and making it hard to cancel).
It is curious there aren't more explorations in increasing stickiness. Though admittedly cable's biggest trick (long term contracts) is maybe thankfully out of reach for most of the streamers.
