You've moved the goalposts. First, you said this:

I’m happy to support devs. 8 don’t like working for free. Not sure why they should have to. And so it’s either ads or subscriptions.

In other words, if you don't pay a subscription or see ads, the developer gets no money at all. You're using the app "for free."

Now you're saying that it's not "for free," just not enough to make a living. And what's more, you're using a mere suspicion to justify your very confident insistence that we need to "pick our poison," and that a one-time purchase is just not an option.

Basically, my point is that you need to choose what point you want to make and stick with it, because your argument has changed dramatically in the course of just two comments.
