To each their own, but I find this decision really misguided.
It's her money, not mine, so whatever, but l do not expect her to turn a profit in, rather the opposite.
In my view, the cross section of "IfR" users and people willing to subscribe monthly is rather small (especially if the money mostly goes to reddit - assuming I could afford it, I, for instance, would rather fund an open system like Lemmy).
And if Apollo's dev Christian Selig decided that it wasn't worth it with an already established paying user base, who already has a strong culture of subscriptions and exaggerated pricings, and one of the highest volume of users, at what probably was the peak usage of the platform; I don't see how a small app like IfR can survive.
That, or he made a pretty expensive mistake...
It's 100% clear that Reddit is trying to kill off third party apps completely so that they can facefuck you with ads and other garbage. The Apollo dev saw the writing on the wall. I can't blame other app devs for trying to squeeze a bit more livelihood out of this, but hopefully they've realized that they need to move on asap. In the end, it's a great reminder to not build your business on someone else's platform, even if they're "cool".
