"Ownership" is something only the HN set cares about. The reason your average person hates app subscriptions the author relegated to a footnote: they mostly exist to trick you into paying for the app more than once.

Folks pay for all sorts of subscriptions, nobody cares about ownership, but when my mom finds out she's been paying $0.99/mo for a "countdown timer" app she used a few times over a year ago she swears off paying for apps for good.

I think broadly your comment is true, and it would be better for the good actors if the bad actors didn't exist. Apple and Google do make it pretty easy to cancel though vs the wild west of the web
