蘋果雖然愛錢但也不會容許那麼沒品的銷售方式存在
Ｎ的這個行為是違反開發者協議的
https://developer.apple.com/app-store/review/guidelines/#business
3.1.2(a)
如果您要將現有應用更改為基於訂閱的商業模式，則不應取消現有用戶已經付費的主要功
能。例如，在您為新客戶引入訂閱模式後，讓已經購買“完整遊戲解鎖”的客戶繼續訪問
完整遊戲。
If you are changing your existing app to a subscription-based business model,
you should not take away the primary functionality existing users have
already paid for. For example, let customers who have already purchased a “
full game unlock” continue to access the full game after you introduce a
subscription model for new customers.
結論：
投訴丟起來，
這種垃圾軟體有種就下架app store~~

範例：
According to the latest Notability update (version 11.0),
those who purchased the app before it was free will only have
access to the features they paid for in the next year,
after which they will be downgraded to the free version.
This is in violation of section 3.1.2(a) of the App Store guidelines,
which stipulates that an app that switches to a subscription model must
provide "full game" to customers who have already purchased a
"full game unlock".
