Once the company goes out of business (or they focus on a different business) they tell you to get your tires or they will be discarded if you don’t. So you have to get them from them and you stop paying for the storage.

That’s where there’s no analogy for media purchased through streaming services. When streaming services withdraw content, the analogy would be the tire shop sending you an email saying “Just so you know, we’re burning your tires next week. No, you can’t come and get them.”
