I don’t want to hold my customers’ data for ransom and cut them off if they stop paying me my extortion money.

You don't have to, you could make it readonly when the subscription expires.

This would be what I’d aim for, absolutely.

I talked to some indies who do this for apps they sell outside the App Store, but none of them did it with App Store apps. I believe they indicated there were obstacles to doing it with the App Store (as it is). I’m definitely not an expert in this — I’ve never had a subscription app.
