You live in a fancy apartment building that has a lobby with a concierge. The building isn't going to give the concierge $100,000 and tell them, okay keep coming back for the rest of your life.
If the lobby of your building has a fancy chair in it, the furniture company isn't going to expect $10 a month forever to keep using it, and on the flip side, if the furniture turns out to be accidentally made of asbestos, it's the furniture company's responsibility to do something about that, regardless of the fact that you're not paying them every month.
Is there a version of the concierge that's a one time purchase? Probably not a good one? The fee your paying is for 1. continued incentive to continue doing a good job and 2. Training and improvements to the staff.
Is there a version of the chair that should be a recurring fee? Maybe if the chair company comes and swaps out the chair every month, but then you're not paying for the chair, you're paying for the chair service. Should the apartment building have the expectation that under a flat fee the fabric in the chair is going to get upgraded to fit new styles and tastes? No, that's never a expectation when you buy furniture. The only case where the manufacturer would be beholden to you would be if there is some gross defect in the product or if there was some negligence on their part that could lead to injury.
Realistically there's not going to be an issue where a chair lets robbers in, but if you bought a door lock for example, and the lock failed when someone tapped it, you're not SOL because your not paying a subscription to the lock maker, they're liable for their defective product.
There's absolutely cases where software should be a subscription model and there's absolutely cases where it shouldn't be.
I don't need any features that have been added to Adobe Premiere since 2013. I don't want or need updates--my copy of CS6 still works. I'm not getting a CC subscription.
If I needed software to help with accessibility compliance, I would absolutely be willing to pay a monthly fee because the standards change and information becomes out of date quickly. It would be an unreasonable expectation that a lump sum I paid in 2013 would still have my websites up to code today.
