For most of this post, I didn't understand the author's argument—how is the inability to offer trial extensions to 0.1% of your customers such a major loss?

Then I got to this paragraph. IMO, it's the most important part of the whole article:

> Let’s say someone signs up for HEY on an iPhone, pays with Apple’s IAP system, and then decides to switch to an Android phone. Billing is entirely messed up now. They can’t update their credit card through the HEY app on Android because their billing info is stored with Apple. And we can’t help them. Who wins there? Apple wins. This creates immense lock-in when all your service subscriptions are tied to a single platform. If you change your phone, do you now also have to change your email address?
