If a user gets value from an app month after month it makes sense for the user to pay for the value month after month.
Shoes and shirts and hats and bars of soap all should have a monthly subscription as well.
That's absurd. I've gotten value from my toilet plunger for years. Let me start charging you a toilet plunger subscription just for privilege of using it when you please. That's your logic.
By that logic, I should be paying Audi and Mazda a subscription for finding utility in the cars that sit in my driveway.
And Nike for the shoes on my feet.
