So 95% of them would have purchased it even if there was no iOS version (as per your original post), but as there is an iOS version 100% of them will now make their purchase using the IAP model (as per the post above)? That seems a pretty unlikely scenario to me. If they're all purchasing in app, then it's an indication that that's where they're using the subscription and that's where a significant value is being added. That provides in some part a justification for Apple's involvement.
