And you can go from Adobe to someone else's software. You can't re-use the stuff you didn't see from your cable subscription last month (DVR not withstanding).
So are TIFFs. The phone is the phone. What is it without a subscription plan? It's a little computer but it's not a phone. You stop paying Sprint, you stop getting phone service. The numbers on that phone or the phone itself is totally different. That's hardware.
Which are useful to do what if you don't pay the subscription to get onto the web? There IS software back there allowing you to do that. And the software stops working when you stop paying your ISP's subscription. Just like HBO stops when you don't pay the cable bill. What good is Safari if you can't use it to access the data on the web you subscribe to?
The services you initially used in your example are the problem. None directly relate to the situation or concerns that CC is driving.
Magazines are the closest. With a magazine, if the subscription stops you still have the old copies. The reason you stopped the subscription is you decided you did not want any new ones.
The other examples are examples of fluid, on-going access to new material (TV, Cable, phone/text activity) or stored material (movies, internet sites, TV replays, social media). Continued access to these is a choice we can make and start/stop easily at our will. Changing access to them (provider) is relatively easy and will provide similar, if not identical experience.
The PS CC situation is a bit different. Yes, we still have the beginning point...the RAW image, so we can start again. Yes, we can have the end point, the Tiff...the flattened tiff. But what about the work product. What if we do not want to start over, just modify one non-destructive aspect of the rendering....that is gone.
It is even worse if we consider Lightroom (which is available separately, but available currently CC). If the CC sub ends, so does LR....where most of the work product is not stored or saved as tiff or jpeg. What a disaster that would be...!!
The point is, the Adobe situation is unique and does, and should, build fear of losing precious work that we have done. Whether Adobe sees fit to work to relieve these concerns is their choice, just as it is our choice to look at areas where we can protect our interests...i.e. other products. And don't get me wrong, I like the products and have a CC sub....I just need to protect my images (just like the Photo CD discussion we had)
