Cigarettes is a consumable resources, as for any resources like that it has fifferen justification as you cant produce it.
The subscription for bed is not, it locks artificially features to pay monthly. Even more, it collecs data to improve the product (which sounds good) - but you need to pay for this. They have an ability to run model locally - they choose to not.
I like Topaz approach: you have an ability over some time (subscription period) to have up to date model that will help you recognise snoring etc, then if you choose not to pay - you stick with this model, but it still works.
Subscription in addition is something that limits an ability to sell it in the future.
