As far as I am concerned, subscriptions are an unreasonable hassle. You need to keep track of what subscriptions are active and where you can manage them. And when subscriptions are running, a “did I remember cancelling all the stuff I’m currently not using” is always in the back of my mind somewhere. That’s just annoying noise that I can easily avoid by not using subscription services.
Just seems needlessly limiting to act like this out of principle.
