Why the Subscription Model Fits This Market So Well
Because the product cannot fail in a way the billing notices. A tool that promised a specific outcome could be held to it; a tool that provides calls provides them on schedule, regardless of results, and the service was technically delivered every day of the month. The recurring charge is therefore never in dispute on the merits, only ever on the paperwork.
The other reason is timing. These subscriptions are most often purchased during a losing run, when the monthly fee is smaller than the amount just lost and the comparison makes it feel negligible. That framing is not accidental, and it is why the sales pages are written the way they are.

Log a hundred of the free calls first. Every paid product in this market has a free tier or an open channel, and the calls in it are produced by the same method as the paid ones. If the free calls are indistinguishable from a coin — and in every test we have run they have been — there is nothing on the other side of the paywall to buy.
The comparison of what each tier actually provides is on the free and paid page, and the overview of the whole market is on the home page.
