Sometimes I think the optimal subscription model isn't to pay for additions to software but to maintenance for a stable environment/OS/API set. Like, I've long since failed to get excited about upgrades to macOS, but I might well pay Apple some yearly double digit number to keep snow leopard stable as long as I have hardware that runs back that far. That way, nobody's software rots out from under them, there's always the environment they first brought it to as long as there are enough people to pay the subscription.
