I subscribed to D+ on day one, but my current subscription expires in a month and I'm not renewing. Even more so after this. Not only the price has almost doubled here in Spain (from 70€ to 90€ to 120€ yearly), but also the amount and quality of content has been abysmal this last year. I've seldom watched it, actually.
Content is not free, sure, but with the price hikes, the diversity of services and all the nonsense about account sharing, I think the TRUE subscription model (a service you pay monthly) is quickly going to turn into intermittent one-month purchases, at least for me. Wait until there's something worth watching, pay for a month, use it as much as possible until it expires, rinse and repeat.
I used to be subscribed to D+, AppleTV+, HBO Max, Netflix and Prime Video simultaneously for about 30€/month (and Netflix was almost half of that). Low enough to not care if I didn't use one of the services for some time. But subscribing to the same stuff in the same conditions now would cost me almost double. Not being able even to share it when I'm not using it is the nail in the coffin.
I abandoned Netflix on the last price hike almost year and a half ago, and D+ will be next.
