Name a single subscription service that never changes over time? If your product is based on another company's service then you are beholden to them.

Electricity, water, TV etc... they basically always work. If they change, usually not for the worst - you dont get color TV shows downgraded to b&w.

The common thread is these are utilities, not VC-backed start-ups wanting to dominate the world.

Well, TV service does get downgraded a lot by channels being removed out from under you.
